Question about 3-d

I woud like to start this off by thanking everyon for all your help… I have learned a lot from this place… Now I must ask for more help =)… I have a few questions about the web site I plan to build…

I am planning on doing a web site in 3-d and so i was my question is

  1. Do i just do the stuff in a program such as Maya, Lightwave or Cinema 4-d and exprt it as quicktime and import it into flah??? and then when i want it stop so that i can have buttons put a stop frame in it???

  2. And how big of a file would you guys say is where i should start to worry about loading issues and how long it would take…

  3. And last of all I have an AS question. If i do a web site where i load external swf’s Can you load and external swf in you mian file that where that external swf also has an external swf inside of it? I dunno if that makes sense but I hope it does
    ( a quick example) : Main timeline loads a photography movie on release and then there are buttons inside that swf that loads a specific gallery?

Hope you guys can lead me in the right direction. Thanks again for the help
