For TCS, motor choice isn't much of an issue, silver can all the way

I'd take any of the quantum comp ESC's for their lightness and small size, but even GTX'es will fit well inside the body. Just set them to regular stock racing mode. You can find these pretty cheap in the used forum, every ESC I own (Quantum Comp 1, GTX, Rapida Pro) I had bought used, and they all still work great. I don't even bother with capacitors or diodes for the most part, it's only a silver can motor..

Serious racers will get the ESC with the lowest on-resistance, the new Tekins look promising.. my main one is a Rapida Pro for my M-04M, the power-limiter is priceless for traction. It's a bit heavier than the Quantums, though, but the on-resistance is crazy low, is fully programmable, and I can set the frequency waaay down..

For a servo, anything like .12s or faster have always worked for me.. I keep it lightweight by using a plastic geared JR 4750. Torque really doesn't matter too much with these cars..
