If you're going to be pimping FS2, might I make some suggestions?
First, make sure you get before and after (the SCP) shots of as close to identical situations as you can get. This will really drive home the advances far more than just after shots.
I also think you should aim to get as many screenshots from mods and TCs as possible - show off TBP, the Inferno Fleet, the SW mod (someone will get the screenies for you I'm sure) etc. etc. Demonstrate what the rest of the community is doing while at the same time showing off the SCP.
Not sure if these'll fit into your overall plans, but I think they'd make nice pimp shots, especially some of Tomcats damn fine TBP ships, and Karmas SW texture jobs.
