forgot to say I agree that the top mods for you are:

1) slower motor - Carson 'Poison' is a very popular choice

2) bearings, you got them already - careful when you assemble the gearbox, there are a couple of bushes on the centre selector clutch ring (part J7) which you MUST NOT REPLACE with bearings. Keep the bushes, make sure you glue them FIRMLY in place into the clutch ring and be super careful not to get any glue onto the inner radius. I you don't glue these in firmly, they can easily slide out of place and then your selector forks will jam up. I have found that the Tamiya glues don't work well for this application (metal onto nylon). I use Araldite to be certain, the gearbox is a b*tch to remove from the truck for teardown if there is a problem after you've built it!

3) steering, as per above
