Carrier/intermediate Bearing Replacement

Good evening guys,

A few months ago I had my R/H drive shaft seal replace due to a leak, and my Mech mentioned that the 'Drive shaft bearing' might be on it's way out. Presuming he meant the Carrier bearing.
Anyway, long a behold I'm starting to hear it  & I have a few days off over Christmas to do it, Although I've never tackled this before.

So I have a few questions;

Will a 300mm Long reach bearing puller do the job? And will these be enough to pull the locking ring off as well?
Is there any hints or tips in getting the R/H drive shaft out or things I should watch out for?
Will a 32mm pipe be right for hitting the inner race of the bearing back on?
Would I be better off just replacing the R/H drive shaft?

Thanks in advance!
