My steering wheel has been shaking lately somewhere in between 60-80ish mph. Nothing out of hand, but you can feel it and see it in the steering wheel if you pay close attention. Don't know if these might add together but here we go, any info would greatly be appricated. Don't want an accident.
I came around on checking the rear tires today and ran into this....

Is this okay? Anybody else have this problem? Or am I living on the edge right now?

Camber looks pretty negative but don't think that's causing your vibration. First thing I'd do is get your alignment checked though. Inspections are typically free. Toe might be off. Could be a balancing issue also.

The wheel is slightly slanted inward from the top on both sides (negative camber). And the tire tread seems to be gone on the inside of both tires, is that the reason for that? I guess best thing is to have them inspected and aligned. Or would I have to purchase something to get the camber/toe corrected? The tires were new but it seems like the inside of them are now worn out.

Could be:
Tire out of balance
Belt separation
Worn ball joints or other suspension parts

A good tire/alignment shop should be able to diagnose the problem.

While you're there, have them check the rear alignment. Tire wear like you have is often caused by too much camber.

If I remember the few posts I've read about rear camber correctly:
A little negative camber can improve handling at the expense of accelerated tire wear.
There is only limited rear camber adjustment on the 370Z.

the vibration is coming from the wheel balance...discount tire did a horrible job balancing them and steering wheel vibrated worse when they balanced the five axis...

I took it to a shop on rancier and they did a better job, but it still had some vibration at the speeds you stated...
