with two servos on each tread
"the greater the torque, the lesser the speed" so if you want to have a greater speed then look for a motor tha has a lesser torque ....
This is probably going to give you a lot of pain. The whole thing would fail/break if the two servos does not move at the exact same speed.
i have noticed though during normal servo operation that the faster you send your pulses ie. the low pulse length, the faster the servo moves to position, this would probably work well for a modified servo (if the low pulse is too short on an unmodified servo, it makes the servo jitter once it reaches position but because an unmodified servo never reaches position you can probably take it right below the usual 20-25ms).

No.You can have high torque with high speeds as well. The best thing to do is do the maths, read datasheets and adjust what you bought by controlling voltage, current, PWM and using gearboxes/sets.
I'm not sure what paulstreats was talking about with the servo pulses. With an unmodified servo. the pulse length corrisponds to a position for the servo with the center being something like 1.52ms,
