1. How many days does it take to go through the museums. Particularly interested in the museums of natural science.
I lived in DC for 3 years, incidentally.
Honestly, all the DC museums are brilliant, and many of them you can spend an entire day in if you want to. The Museum of Natural History, the Museum of the American Indian, the Museum of American History, the National Portrait Gallery, the Museum of Art, the National Archives, the Smithsonian Zoo, the National Air & Space Museum (and their annex by Dulles airport, officially called the Steven F. Udvar-Hazy Center), the Hirshhorn Museum, and the Museum of African Art are all great and worth a visit. The bigger ones (Natural History, American India, Air & Space) you can spend a LOT of time in. Most of them you can see the highlights in just a couple of hours, though it depends on your degree of interest in the subject material. The American Indian museum is really worth a visit, and does not make efforts to whitewash the history to make white people look less terrible, which is especially refreshing. And those are just the Smithsonian museums, there are also a number of great private museums. The Newseum (basically a history of journalism) is great, including a section of the Berlin Wall and a piece of the radio tower from the World Trade Center. The Spy Museum and Crime & Punishment Museums are great, as well. Other good ones include the Corcoran, Dumbarton Oaks, the Shakespeare Library, the Frederick Douglass home, the Laogai Museum, the Library of Congress, the Marian Koshland Science Museum, the National Arboretum, the National Building Museum, the National Geographic Museum, the Phillips Collection, the Navy Museum, and others.
In short: it is hard to give you advice without an idea of what you are interested in seeing, because there are essentially limitless options. It is also worth looking up events for the time you want to be here. For example, if you come in the early spring you can see the Cherry Blossom Festival, during the summer there is a being Latin American Heritage Festival, there is a great St. Patrick's festival, etc.

2. Are there any tours, or do people advise us to just wander by yourself
There are lots of tours. There are private tour groups that will take you to various museums, and most museums have their own staff tours. However, unless you are traveling with people who don't speak/read good English, it's probably not worth the money. Wandering by yourself is more fun and less stressful, and looking by yourself you can find lots of good spots that avoid tourists. Like the Sculpture Garden, the MLK Memorial, the FDR Memorial, etc.

3. What else besides the White House is there to see in Washington DC.
In addition to the museums there are a lot of monuments and such. Depends on your interest in US history. The Washington monument you have to be an idiot to miss, especially if you go to the White House. The Lincoln and Jefferson monuments are both great (I prefer the latter, actually). The World War 2 monument is beautiful. So is the Reflecting Pool, the Vietnam monument, the Korean War monument, the MLK Jr. monument, and the FDR monument. All of these are in a relatively small area referred to as the Mall. Easy to find, and there are plenty of posted signs.
Further away from the Mall, there's Georgetown (which includes Dumbarton Oaks, which I mentioned above), which is a beautiful old part of the city (great place to get dinner or drinks, but it is expensive and doesn't have a Metro stop). There's Arlington Cemetery, which is pretty and neat, but again mostly interesting from a historical perspective. Embassy Row is a fun place to walk around (and if you go the right time of year you can go to one of the various Embassy open houses they have, where they invite you into the buildings. When I was last there I had wine and cheese in the Argentine embassy, and the Japanese embassy had a display set up of traditional Japanese artwork). There's Great Falls, Rock Creek Park, the Baltimore and Ohio Canal, and the Manassas Civil War battlefield all close by, as well. The National Arboretum is also worth visiting.
A day trip to Baltimore is also worthwhile.

4. Any particularly good restaurants I should try out.
What are you going for? I am assuming you don't want to go the fast food route (if you do, that is readily available everywhere). Georgetown is the best place to go for nicer restaurants. My recommendations there are 1789, Filomena, a place called Farmers, Fishers, Bakers, and Sea Catch (though to be honest I rarely went out in Georgetown, I was poor while living there). Old Town Alexandria is also a great place to go for dinner/drinks, though it is a bit far from the city proper (but easily accessible via the King Street metro stop). That was always my favorite part of the city to go out to dinner at. My recommendations there are The Wharf, the Fish Market, the Chart House, King Street Blues, Bilbo Baggins, Gadsby's Tavern, and Virtue Feed and Grain (there is also a great Thai restaurant whose name I can't recall). The other good areas are Dupont Circle (which also has probably the widest range of options food-wise, both in terms of style of food and price. There are nice restaurants there all the way down to hole-in-the-wall burger joints and such) and Woodley Park/Adam's Morgan (which is the cheapest). The latter two areas are both relatively close to the embassies, as well as being the best areas to go out drinking in after dinner. There's also Chinatown (though those are mostly chains, except for a couple decent bars), Ballston, H Street (hard to reach, though, due to the lack of a metro stop), and Eastern Market. There's a scattering of stuff downtown, too. The best thing is to either look something up in advance or just walk around one of those neighborhoods I listed. DC is a pretty small city, geographically, and everything tends to cluster close to Metro stop entrances.

Oh, and if anyone thinks I should see some other part of the US, feel free to suggest it.
All the places you listed are worth multiple visits, potentially. Other places worth seeing (depending on your interests) are Baltimore, Philadelphia, Chicago, Miami, San Francisco, San Diego, Seattle, New Orleans, and Austin. Those are all major cities with lots of opportunities. Some smaller cities that aren't worth gunning out of your way for but are worth visiting if your trip happens to take you to the area include Charleston, Providence, Asheville, Nashville, and Portsmouth. And those are just cities, there are also natural attractions like the Everglades, the Grand Canyon, Zion National Park, Death Valley, Yellowstone, Yosemite, the Smoky Mountains, the Great Lakes, the Outer Banks, Glacier National Park, etc.
EDIT: Seriously, the US is fucking HUGE.
EDIT2: If your trip includes having a car (as opposed to getting around my train/bus/plane), you can also use
this website to find lots of weird, strange roadside attractions all around the country. Want to see T. Rex statues eating dummies dressed like Civil War soldiers? Well, that's the website for you.
