Starting with this question, and will get to your gearing questions soon!

You can use a y servo harness, to spilt your throttle channel to the esc and the brake servo. However the brake servo will move with the throttle and unless you have a really fast servo (like a jr9100s) you will notice a lag in braking when going from full throttle to full brake. Not a huge deal but it will take some getting used to if you currently run a brushless setup with the motor doing the braking.

I would say that having a radio that can mix the 3rd channel with the throttle channel is much better. I have run both and the mixed setup feels alot better, and gives you alot more control over the brake servo. I had mine set so it did not move when the throttle was moved in the positive direction, and only moved when I moved the throttle backwards to brake. Depending on the radio you use (I had a futaba and the guy who wrote the manual was on heavy drugs!) it may be a big pain but is worth it.
