Well, if you're going to use four MOTORs, and not servos, you're going to need at least 4 PWM ports. The AtMega8 (the MCU we usually suggest for beginners) only has three. Also, depending on how you control the arms, you might need more, but probably not. Other than that, everything (except the camera) can be achieved with most MCUs. I really don't know about the camera, someone else will have to chime in. It all depends on the number of inputs you need.

It all depends on the number of inputs you need. I'm gonna try to have 2 motors (2 wheels per motor), but if that doesn't work, I'll go for a motor for each wheel. And btw, the arms will be controlled by servos. They'll probably be 3 DOF. And what about the bluetooth? I need UART for that, right?

another question,
What would be a good microcontroller to use. I don't have any language preference, but a light weight one and one that is not too expensive would be best.
a 4-wheeled robot (wheels driven by motors) with 1 or 2 arms, and controlled from my computer via bluetooth, and I might add a few sensors.
