Rear end bouncing after new shoes and drums
Still no luck with this! I had my wife drive it and lock them up in front of me, wanted to see if the rear is bouncing off the ground. I noticed when she slammed in the brakes I saw a shot of brake fluid come out, bingo I thought! So I replaced wheel cylinder and bled brakes still nothing. Completely stumped with this

I'm still getting a slight shake in my truck since I did the back brakes too, but it has gotten better, especially since I did the front brakes. It was worse before I did the front brakes because they were not working at all so all the braking was done from the back, which may have caused overheating and damaged the drums. I didn't skim through all the posts here, but at any time did you try and have the drums cut for out-of-roundness?
You probably already know this, but I thought I'd mention it just in case. Did you completely clean all/any brake fluid off all parts on that wheel before reassembling it?

If your shoes got brake fluid on them you need new shoes. They are porous and you will never get all the fluid out of them
Wow, I can't imagine your frustration, although I had my fair share of vehicle problems. So you have all new parts, including drums and wheel cylinders and you even replaced the shocks, which others have said may cause similar problems. Another cause may be tire size versus shocks used whereas the tires may be the cause, but you said this all started after the installation of the brake parts, so that probably rules out the tires.
I don't know, but all I can think of is the possibility of parts being wrong for your truck. Did you double check all parts to make sure they are exact in width and size? I know when I installed my brake shoes and wheel cylinders, NAPA swore they gave me the right parts, but the wheel cylinders where different and I had to match them up before installation. For example, let's say your drums were slightly larger than they should be (if that's at all possible). That would cause your wheel cylinders to push out farther than they should causing a possible leak in brake fluid and wear on the top of your shoes.
With that said, could this have been your cylinder leak and not the cylinder being bad? Just thinking out of the box right now.
Also, looking at your pictures of the install, your brake shoes do look more warn on top, which may be normal, or may not be. If not, maybe the above scenario may apply. I don't know, I'm just reaching out to some crazy stuff right now. You never can tell. Sometimes the answer is right in front of you and sometimes it's something crazy and not normal.

Yeah I’m stumped, the only thing I find odd is that the adjustment wheel has to be all the way in, in order for drum to fit. This has to be something with the brakes, I’ll take the drums off this weekend and see what the pads say
No, your shoes are thick so no adjustment is needed. It'll expand as they wear down.
Tomorrow I’m going to replace the front rotors and pads and take it from there. I have a squeal and I’m not sure if it’s coming from the front brakes or rear maybe I didn’t put enough grease on friction points?
If it's only hopping when you are hard on the brakes, it's a brake problem. Even with brand new shoes/drums, I would expect to have to do a fair bit of adjustment for the brakes to be correct. Can you post pics of your brakes with the drums off?
