alex, what yer tryinta do is not gonna be easy for a 3d newbie. this may be why they didn't have an answer. it requires the complete reading of several software manuals IMVHO. I have used sketchup pro, but I didn't see any way to do a fly-thru like that, nor to export a flash- controlled animation. but the first step is to do the fly-thru animation in 2-5-second cuts. once ya do that, and learn how to use flash to turn it into an user-controlled website .... unfortunately the flash animations I've seen are very limited - rotation, reverse/forward, zoom. what yer tryinta do is more like a video game.
