I got a 4-2-1 header a while back from eBay an it had two places for 02 sensor the first is when the header goes from 4-2 and the second is from 2-1. I read that the o2 sensor should be able to be hit with exhaust from all 4 cylinders is this really important that I should relocate the o2 sensor?

You should be fine with just keeping the o2 sensor where it's at.

I also installed a sunpro air/fuel ratio gauge and it says I'm running so lean that it won't even register so I'm wondering if relocating it will help it work better or if my o2 sensor is fucked haha

Best way to check the o2 sensor is by using an ohm meter / multimeter. I don't remember what the numbers should be for it to be working properly but you can find it easily on google. For your o2 relocation, it still shouldn't matter.
