LOL I have been messing around with Unity for the last 3-4 weeks as well... switched over from GameMaker to try some 3D stuff.
Not sure how much I can help... not really good with exporting 3D models or animations... I think I've got particle systems and some basic 3D vector calcs down though.
Right now, and it took me three weeks, but all I have is a jet combat simulator with rudimentary enemy jet AI, homing missiles, some GUI elements, "Danger Zone" playing in the background, and a floppy-eared puppy as the player model:
