Posting multiple threads is never a smart move if you want help. most users here will read every post so your post will be seen.
its not really a question we can answer for you regarding the hardware as its up to you how you want it to look.
You can select a leg type from here:

http://www.lynxmotion.com/c-9-electronics.aspxthere are a few current threads on here about quadrupeds and all are slight different is design and electronics so you could look into those and find out whats the best way for you to control it.
my choice at the moment would be to use the BotBoard2 with a basic atom chip and an SSC32 servo controller. and then of course the PS2.
The Bot Board II is a carrier for the Basic Atom microcontroller. (Brain)

http://www.lynxmotion.com/p-869-ps2-rob ... er-v2.aspxsome people are using the Arduino based boards and so this is another option for you but the setup is basically the same.
There is not Lynxmotion Quadruped code avaliable YET, but as i have mentioned there are a few projects out already and im sure people will be happy to share their code..
Me included.
