Yes, all 350's, 20d's, 30d's have amp glow. The 300D have 2 amp glows. Amp glow can be subtracted from dark frames.

The 30D and the 20D both have the same cmos sensor. the 30d have all the additional bits and pieces such as bigger LCD screen, iso3200 etc but for astro imaging, no difference here.

The 20DA has liveview whereas the standard 20d don't. If the standard 20D is modded, it is a much better camera than a 20DA for astro imaging. However, the 20DA is also build for daytime photography but you certainly can use a modded 20D with UV/IR for daytime photography also with correct CWB. in regards to this, the 20DA will be better off for daytime compared to a modified 20D.

Also is the Baader ACF II filter the same as a UV/IR Filter?

Yes same coatings as the UV/IR.
