Emerald is NOT able to do all of that. None of that, in fact.
In any case, the X-tra editor is vastly superior to Emerald.
X-tra editor can be downloaded
here.
As for the questions themselves:
1) Unit colors? I just do hex editing. Basic tutorial and listing of colors is
here.
Difficulty: medium.
2) Modifying unit attacks? Well, the examples you listed have several different ways...
Giving a unit with an attack a different weapon, or modifying weapon range: Able to be done in Arsenal 3.
Difficulty: Easy to medium/
Giving a unit WITHOUT an attack an attack: requires Stargraft editing, giving the unit an attack button, Arsenal 3 editing, to give the unit a weapon setting, and ICE editing, to give the unit an attack animation.
Difficulty: advanced.
3) Changing unit ranks? Can be done in Arsenal 2 (available built-in with Stardraft). It's really the only use for Stardraft these days.
Difficulty: easy.
EDIT: CWDs only work with Starcraft version 1.08. Either reinstall and update it to that, or do a dual install.
EDIT, Mark II: So you know... I am to Starcraft editing what Spanky and Utsanomiko are to Evangelion.
