Pins should be good unless a boot is ripped and/or a pin is seized. It's always a good idea to replace the shims. Most pads come with them. There is no hardware kit for the park shoes. Unless they are down to metal or damaged, they shouldn't need to be replaced. They shouldn't wear unless you drive with the park brake on.
I'm in the middle of this same job myself. Since I've got a rattle on the passenger side, I did purchase new e-brake shoes, and can't wait to see what I find when I pull the rotor from that side. I actually use my e-brake when parking (since the lever is in the 'right' place) and I can tell the passenger side isn't really engaging. Now that I see how the thing is assembled on the other end, I'm betting that I'll find the shoe off the mount on the passenger side.
There's a 'cylinder' between the two ends of the shoe / adjuster wheels. Looking to see if / how that would be serviced / replaced (like in the old drum brake days) Thankfully, there aren't spring assemblies to take apart / reassemble.
Sorry for the hijack - at least it's on-topic
Oh - and I went with Napa all four corners, too (adaptive one up front). Planning a fluid replacement at the end, too (separate thread, since I have questions about doing it 'sans helper') ...lol.
