if have breadboard power supply connected 12v adapter on wall outlet, , jumper pins on power supply set 5v, possible use power source , have arduino controlling while connected computer via usb can still send code it?
i'm asking because figure if project requires 8 servo's, 10 led's, stepper motor, , few other things, i'm assuming arduino won't able power these things on it's own, why not use external source right start.
does make sense?

yes. connect grounds, not connect power between arduino , stuff it's controlling. arduino powered off usb, else off power supply.
you'll damage board if connect 5v on arduino 5v on other power supply while it's connected usb (while it's *not* connected usb, can power arduino through 5v pin, not recommended, because you're setting trap - plugging usb cable in damage hardware)
