in the terms of bearings for speed improvement as long as your bearings are spinning freely, dont feel gritty or have slop you are pretty much good to go.
Now you can go the route of maintenance nazi and clean your bearings after every run and replace all bearing once a month. But this can be overkill but you will always be on top of the current condition of you bearings.
Now there are certain areas of the car that more attention to the bearings is required to help prevent more costly repairs. Motor bearings I always advise checking after every track session. Next would be bearings along the drive train like diff bearings and diff pinion bearings for 4wd and all the bearing in the gear box for 2wd.
As for the bearing at the wheels as I stated earlier spin freely, dont feel gritty and free of slop.
Bearing companies are like anything based on experience with the manufacture. Acer bearing, Boca Bearings and Avid bearings are the bigger names for RC bearing and the general opinion is they all make a quality bearings that should serve you well.
In the world of bearings there are two ratings to go by. ABEC which is rpm tolerance and then Grade which level of the materials used in bearing.
