brushless don't require you to work on them or put new brushes in, also they are more powerful, you need a motor and speed control, look on ebay etc for brushless combo... you will find a load, you want 10t roughly for drifting, i run a etronix photon its cheap and cheerful, does the job and it has uk warrantee so its replaced if it breaks.
modelsport etc is a good place to buy from, tbh i would recommend a yokomo drift package even if its just for playing with, if you wanna get more it to it they can be set-up and upgraded easy, i run counter steer on my cyclone, that means the rear wheels spin faster than the front meaning once sliding you have to steer in to the drift so its more realistic and harder to do.
radio gear go for 24mhz its just simpler and works better.
then bodies... they go from about 20 quid... up to whatever lol, i know people with 100 quid plus in just 1 shell lol, wide arches, spoilers, lights...
