Flash Mx Junkies Help

Hello everyone,
I need some help here. I'm working on this project where I'm importing AVIs into flash movies which inturn will be loaded into a base movie. Now when I import the files Flash configures it to the frames per second of the movie that I imported the movie into. So my AVIs are not running at full speed. I know I can change the frames per second of the Flash movie but isn't there a problem with loading movies of different speeds into each other? I'm not sure. I have never really tried, I just heard this. Also.. I'm a true right-brain and it sucks because I want to understand actionscript but it does not compute well. I can create sites that work well but they like the dynamics say of 2advanced because of the code end of it. Does anyone know of some places that I can go that teach some Flash MX tricks or easy ways to learn actionScript?

Thanks
