Well, a good balance about performance for a 2wd is a 8.5T motor. Not too big, not too slow. You can start with that.
About the ESC, start with at less 60A, you can use a bigger motor if you want, the esc will warm less and the power will be enough. You can buy a 120A as well, but it's more expensive.
The cheapest esc are sensorless, it's enough to begin, but if you want to change the motor, maybe you couldnt find any good sensorless motor, and if you take another motor witch is sensored, you'll not sure it works correctly.
The best choice could be the ezrun combo, cheap, good performance, sensorless or, the xerun combo, a little more expensive, but sensored and good performance.
