Whats Next? Please help me out

http://www.newclearprojects.com/myflashsite.gif

this is what I have so far for my full flash site. Could you tell me if the way I have it set up now is logistically correct. Should I have those two movie clips on different layers? I also have a nother question, maybe someone can point me in the right direction. When I click on one of those buttons on the right hand part of the site I want a picture to load in the left clip and content in the right clip. I know I have to create separate swf files to load in those movie clips, but I get confused in AS when doin loadMovie() cuz im a newbie. Could some one give a lil help. Thanks.
