I am thinking that I have a loose ground somewhere causing my temperature gauge, fuel gauge to read random amounts. my tachometer stays reached constantly. Where are some locations that I can find grounds so I can check them?

While it could be a loose ground I would suspect it's the common GM dash problems of bad stepper motors and bad solder joints. There are quite a few places that rebuild them. Just search for GM Dash repair.
