Also on some of the pick up selections there is a slight buzz. Should I just get them adjusted or looked at or replace them?

I own an old Squier as well, don't play it anymore, but it was my first so I kept it around. The slight buzz you're hearing on some pick-up selections, mostly middle and neck, is due to the fact that they are single coil pickups. You won't be able to get rid of that buzz, single coils are just noisy. Hence the name for humbuckers. "Hum......bucking." They buck the hum of the often noisy single coils.

As far as the problem with tuning, I never figured that out as well. I just never used the trem arm until I get a new axe with a Floyd Rose. But those do go out of tune quite often.
