I have seen some people say I need to lock this at 33.3mhz, and I have seen some people
say set it to the cpu, and others say leave it to auto?

What should I do here? I see a lot of people saying different things, but no reasons why.

PCI-e runs at 100MHz, PCI runs at 33. With most modern boards when you set it to auto it should leave it at those values.

modern boards lock busses automatically. the systool reading is weird, so in your bios change it from auto to 100mhz and see if systool reads it right then.

Most decent motherboards will allow you to lock both PCI and PCI-E busses. I don't know why some people try and OC these busses, the gains are minimal if anything, and instability increases dramatically.
