Thanks for the responses, I swapped the pads around, no help. So I swapped 1 pad from each side to the other, made it a little better.
At that point I could at least get the caliper over the pads and rotor without a rubber mallet, but it was still binding, so I took my thin crowbar to the "window" in the rotor. Seemed to move the rotor enough to allow the pads to back off.

No issues anymore, car rolls back on hills again, and no overheating (these things were so hot I couldnt even take off the wheel without gloves). Drove it about 15 miles on the highway to get home from where I was working on it and there were no issues at all on the way home!!!

So I think that what might have happened is that the caliper pistons werent actually fully retracted? Or maybe the slide pins were jammed up? I checked the slide pins when I pulled the caliper off and they moved freely, and had plenty of grease on them still, so I'm honestly not sure what the issue was.

Are brake pads R/L AND inside/ outside specific?

The brakes weren't too glazed so I just popped them right back in, they only had about 60ish miles on them.
