There is some sort of weight attached to the bottom of my rear diff (and i'm sure it's on your rear diff too). I've been staring at it for the last 4 years, and i'm assuming it has something to do with controlling wheel hop or dampening the forces from the driveline, but I'm not 100% sure. Any thoughts? And any idea what would happen if I remove it? It seems like I could shave 20lbs off by getting rid of it.

That would be the "dog bone". It reduces vibrations in the driveline. Some say take it off, some say leave it on. I say I don't want any vibrations.

Its to help with vibration in the driveline. They say if you go with a steeper gear you can remove it without any vibration issues.

i didn't reuse it, but the bracket is there for the pinion snubber, the thingy that stops the axle from hitting the floorboard/chassis

so you didn't reinstall your snubber? I was wondering if it could be bolted back in after the weight was removed. I'm gonna play with mine when i drop the gas tank and install the fuel pump.

It is not usless dead weight as some suggest.
It is tuned to the drive shaft critical frequency and not the gear ratio installed.
If you install shorter gears that means that you will reach that critical frequency at a lower road speed.
By all means remove it if you want to but keep everything on hand just incase you have issues like I did.
my car just about shook it's self apart at 80mph.
