Can I press them in myself or should I bring the rim and parts to the dealer to do. Should I change the seals too or just the bearings. Thanks again for your help

If you turn them with your fingers and they feel smooth, you dont need to change them. Its easy to change yourself, knock them out with a screwdriver from the backside. When you replace the new one, use the old one on top of the new and knock them in. If you have a press its even more easy, if seals are good you dont need new.

About rubber, try to push the bike while is in gear and look for the free play between sprocket carrier and hub. I am not sure, but if there is a free play bigger than 5 mm I will pack some inner tube inside the hub or replace them if more. But, again, I am not sure.

When you put it back in to the hub, it supposed to be thight. No freeplay in the chain direction back/forward.
