One of the camera options is a airfield one. i think its f11 or f12 or something around there. You can use the scroll wheel on the mouse to "fly" it around.
Also if you are flying the su-25t campaign there is a user edited version that fixes some bugs and problems with it, alot of the time updates can break the missions in the campaign.
For 2.0, only the Nevada/NTTR terrain is availble. 2.0 uses a new map engine so the black sea map is currently being upgraded to it but it is not out yet. Most people are currently flying on 1.5 as it is pretty much stable and the performance is improved over 1.2
The BDU bombs are inert training bombs. Pretty much useless in combat missions. ALQ-184 basically the same as the other jammer, just has less drag i think.

You can also use the Shkval to track targets using the gunpods in programmed mode. They only track vertically so you still need to fly over the target.
