Is this set up any good?

Seems fine but no experience with that make, main things are range, glitching and consistent responses.

KV = number of rpm per volt.

You can get 540 brushless motors as x.5 and x.0, I ran a 7.0 for ages in my 2WD. Most are x.5 but big thing to look for is sensored or sensorless. Sensored is best as it gives finer control. Confirm KV = rpm per volt but it is only a rough gauge of a motor, torque and feel is harder to measure.

I went for a castle 'mamba max pro' mainly because it seemed to be capable and scored it cheap off ebay!

Agree a program card is probably needed. Castle are popular in the bashing scene but I have not used one for racing. It is sensored so should be fine.

You are correct the motor determines how much current is drawn, you just need to make sure the ESC and Battery can deliver it. A 4500mah battery rated at 50c can deliver 225 amps but it will probably have a peak rating and a continuous rating, the peak might be double that. Most ESC have continuous and peak ratings as well and will have a max motor capacity either stated as kv or wind number.
Also, note that battery manufacturers are sometimes generous with their power ratings. I have raced 25c batteries that spank another brand 100c on punch.
