Advanced Navigation how to?

Hey, i looked around and couldn’t really find an explation of what I need. Here’s the flash i’ve been working on, what i have so far:
http://free.hostultra.com/~zero25x/site_content.html

What i wanted to do is when u click a link, the abstract bubbles retract (or appear to retract using a mask) into the middle square, then the square glides over to the right, and a bigger box appears on the left/middle side, then like clicking back to home the bar slides back to the original place, and the bubbles come back out. but doing a animation like this for all the links, like having it move to the left for one, right for one, ect.

how would i go about doing something like this?

Flash twists my mind :red:
