2) Obi-Wan did say "Old folk's home"

3) In the gunship, the pilot says they're out of rockets. Yet we can CLEARLY see rockets under the wing.
Joking aside, It's the Geonosians who were contracted to build the DS, not the Empire proper.
A single planet built the thing

We don't know who constructed the DS, but it would be illogical to believe that they created the DS yet had no members on its senior staff. I find it unreasonable to believe that the Geonosians constructed the DS, though they may easily have designed the basic plans for the structure. Further, without a planet (really), it is highly unlikely that they would have the industrial capacity to construct such a battle station. I find more traditional interpretations of the matter of construction of the DS to be more likely.
As for Obi-Wan, "Old folk's home" is a code in the Jedi Order, meaning that he wants to have his message sent directly to the Senior Jedi, which it was (it went straight to Yoda and Mace), though I kind of agree that as a colloquialism it's kind of out of place.
The worst example of something that they did wrong, IMO, was losing Obi-Wan during the shots of Anakin fighting Dooku. One shot, Anakin jumps forward to save Obi-Wan (ironic, given his similar save of the Emperor from Luke in RotJ), but in the next shot Obi-Wan is nowhere to be seen.
