Trucks - Randals or Paris, doesn't really matter. I believe KS boards only come with the Randals option.
Wheels - Personally I have a huge affinity for BigZig Limes, but you will need to be buying the more expensive KS board (Schimitar instead of M1) or the cutouts won't be big enough for them. If you are going with the M1 then I would suggest some ZigZags or some Gumballs or Flashbacks.
As for bearings might as well just get stock, when you first start bombing hills you will probably be quite happy to not be going any faster anyway lol.
