Help with rear wheel bearing, axle seals and cat converter.

My 02 tacoma v6 trd hit 153k today and I decided that it's time to change some stuff out. I am going to be doing rear wheel bearing, axle seals, and I have been told my cat is pretty plugged so a new one of them is needed. I have tried using the search and couldn't find anything on the stuff. Is there a certain brand I should buy for the bearing and seals? Which do people like the most? I do a quite a bit of off-roading if that matters. And last is there different cats? I googled it and got confused on which ones are which. Any help would be great!

 

I forgot to note that I do not have ABS brake

 

If you have the TRD E-locker, your rear has the provisions for ABS. Regardless if the truck has ABS or not.
There are a bunch of subtle issues to be aware of with the ABS type rear. I used OEM parts. The OEM bearing can be had these days from various parts houses for a tad less than online discount Toyota dealers.

Here are a few links, the issues are spread out a bit so read all of the posts.
