i was curious if new wheel bearings would do anything all or just be a waste of time, i heard that they can help your car alot but im not sure, are there good brands that i should look out for?

probably a waste of money. get some tension rods instead.

yea wheel bearings wont do anything unless they are really bad. IF you hear them squeking then you should probably do it. The friction of a bad wheel bearing slows you down a little.
