Topic: Avengers trailer help! Iron man?

I am currently making the Avengers trailer in LEGO (this one here...  http://www.youtube.com/watch?v=tY9DnBNJFTI  ).  I need some help with effects, I have iMovie, iStopmotion, GIMP, Saberfx, and Adobe Flash CS5.5.  I really need some cool effects for Iron Man (Arc Reactor and eyes glowing, HUD display(one quick scene), and flying ( like the scenes near the end, with all the shooting).  I also would like any suggestions on how I could do the very last scene...
If you have any ideas of how I could do ANY scenes in the trailer with the above programs, I would REALLY appreciate it.  I'll post a few WIP shots later this week.
btw, I'm shooting at 24 fps so I can match the trailer download perfectly.  I really like it so far, but I don't want to ruin it with bad fx. 
Thanks for any help you can give me!
