Panoboter bender_328 ?

I'm a newbie, both in Arduino and in electronics, so for me is very difficult to find out, for example, if the servos have to be modified to work at 360° or is not necessary, how many components are needed (and their characteristcs, in the diagrams there are some resistors and capacitors), there is an optocoupler in the list but I don't know where has to be placed on the board, also I'm not able to see how to connect the camera, how to connect the two boards togheter ... probably I'm too newbie for this project ...
