It's all about the way you drive the car and your preferences. But I would suggest to use digital high speed servo for Steering, and I think digital for steering is important because it is so presiced and centering is much much better then analog and the best part is it has great holding power under high speed sweepers.
As for throttle, depends on how your car set up, say you have front oneway and rear diff, praticially you cant use brakes then any kind of servo will do since pulling the carb does not require much power. And I think anything over 50oz in torque will do but try to get something that moves a little bit faster, say 0.13sec 60d with about 60oz. Anything more will be a waste of money for throttle on 10th scale. Unused torque and also it will drain your rx pack fast.
Personal opinion on Steering Servos: JR DZ8450, KO PDS2143, Futaba 9450 or Hitec 5925, That are all in the 0.08sec league and around 100oz in torque.
As for throttle, Hitec 525mg will do a good job. 0.12~0.13sec with 57oz, the best part is they are relative cheap compare with other brand.
Hope this would help!
