Hi Alisdair
I would suggest a small linear actuator for your steering servo as they have a digital feedback built in. It may be useful to add a heavier cutting disk to get some gyro stabilization, as I found out with stock cars the hoops just help it keep rolling until it hits something, better with a active roll arm that can right the mower, using another linear actuator.
You can get a small speed control on fleabay for cheaper than you can build one, one each side with digital to replace the pot and you got it all.
All the best
