Ballbearings is a good first choice. If you are new then I would wait before buying other tuning parts. You could easily spent a lot money on tuning parts for this chassis. Just wait and see what is not like you would want it. The Raikiri is a decent choice.
You run on a parking lot or track? The latter, then ask what the other guys run and have fun with and join them

For battery just a normal 2S lipo with around 6000mah. Servo should be medium fast 0,09s/45 degree, around 60$. Transmitter is a little religion. You can go for a cheaper system for the first months. Then if you love it and want to get more serious, go for a Sanwa system (MT-4 or equal). This is of course my personal experience. After the switch to this brand, I never had any problem and could do a better job more easy on track.
Colorwise should the normal Tamiya PS be the best for the first race livery.
