'66 Barracuda rear axle question

So the "mystery noise" seems to be my Right Rear wheel bearing. I pulled the diff cover off and the ring/pinion looked perfect. Added some primo synthetic axle lube (that my buddy snagged from the jeep dealership he works at haha). The noise is still there, I was pretty sure it was a wheel bearing thinking about going out and its slowly but surely getting worse. Sounds like a perfect weekend project! woohoo

Ok, question . . . I'm still fairly new to the whole RWD muscle car gig and these early A-bods are a bird of their own. I've got the stock 7 1/4 axle, what kind of bearings am I dealing with here? Are there just a set inner/outer that the drum mounts on? Is there another bearing hiding somewhere along the axle or towards the diff?
Would anyone be so kind to give me a little play-by-play how to do this bearing swap? Do I need to pull the diff cover; I've heard the 7 1/4s don't have clips holding the axles in.

Last question . . . how about which bearings to use? Any company makes better ones or just go with whatever NAPA has?

Thanks!!!
Its been about 1 1/2 months of owning this sweet car and I've put over 2,500 miles on her already! Gotta love it :)
