There was also metal shavings on the transmission drain plug, and for some reason shifting is worse after changing the fluid. I used Redline 75-90 GL4 in the trans and Valvoline 80-90 GL5 in the diff, the car was level when I changed them. Here's a link to a video of the sound the car is making.

Lol no shit.
You have a direct line to the rear, you're hearing differential gear noise. The s13 transmits a lot into the cabin, and more solid aftermarket parts will increase that tendency greatly.
Metal ends up in gear oil. Not like it can leave.
Shifting is harder because you put in something thicker, and maybe better, than what was in there. Maybe stick some friction modifier in there. Your syncros are not grabbing as fast because of the higher viscosity/film strength, so the gear won't engage.
If you want less noise, replace parts with OE rubber, non performance stuff. If you want performance, get used to hearing your car. Old sports cars are loud.
