I don't think the arduino board with its mere 5v of output can put out enough power to power some motors and servos I have. Is there a way I can connect these to an external power supply like a power cord or wall socket and still have them controllable with the arduino board without overloading the arduino with too much amps or volts? I appreciate any help I can get.

See your other post - dipmicro has a lot of wallwarts that can supply all the current you need.
You have some transisters or H-Bridge chips to drive the motors?
Servos just need an output pin & the servo library as far as I know.
