...curious if there is a way to repair, erase, or whatever...
Probably

Maybe you buggered the serial programming and/or reset bits.
This is a good point, sounds likely

The solution is a HVPP, High Voltage Parallel Programmer. It applies 12v on the reset line, bypassing all fuse settings. There is a few guides on the internet showing how to build one (If you don't have an STK500 or AVR Dragon). Really useful if you want to play with the fuse settings and fix your AVRs afterwards!
Yes, and I put together a guide that I think is easy.
I recommend go ahead and read the fuses to see what you did: HV-Rescue-Simple
Use a fuse calculator to better understand the fuses:fusecalc
