How to get a nice flow

I want to build a kind of mindmap, starts of with one big button. Lets say it says “start” when you click it lets say it grows abit and sprouts out 2-3 lines that creates new small bubbles. This kind of tween I should be able todo might be abit tedius but I think I can do that. My real problem comes after, if I now want to click on one of the new “nodes” then I want to have a camera like effect where the screen follows the user and zooms in on that node and creates 1-3 new sprouts with new nodes on.

To get the feeling of walking in this mindmap. How do you set this up? Im useing CS3 and AS3. I was thinking useing tweens to get the buttons to grow and to get the sprouts to grow out and give new nodes, but I dont know how to make the camera view change in a good way, I guess I have to use alot of frames how should this be set up. Do I need many many frames so that I have one for every frame of the camera change so to say or can this be done with tweens in a good way that I havent been thinking of.

I understand that this question is very strange and can be very hard to answer but Im happy with any respons I get, I just need to get my thought running if you have anything to say any tips please tell me, Im still very new at flash just started working with it now and started right off with CS3 and AS3. I need some tips of the general flow.
