I basically have the same set up (aside from the shocks, I kept mine stock). I'd say instead of buying the brushless system, go for a BB2 motor and Lipo. It gives good speed indoors and outdoors, is relatively low maintenance, and a whole lot cheaper. For the steering rods, use a guitar pick (I used one of my sister's old ones) since its cheap and lasts for a long time (the ones I made haven't broken yet, and its been about a year). And as for the metal gearbox, I never bought one and I personally don't know the benefits, so I'd personally skip that one since the stock gearbox is fine.
