Ah-hah! Stuck thermo! Simple, isn't it? Remember this. If the head gasket was blown, you would be getting pressure in the rad BEFORE it gets hot. I had a blown gasket on my Chevy that spewed antifreeze out the overflow that was still cold! To check the stat, put it in a pan of water on the stove and watch as it heats up. Just don't use your wife's best pan, she'll get pissed!
Been there, done that.

So new tstat in and now shes over heating again! Radiator cap is no longer getting hot to the touch and the return line from the water pump to my heating core isnt getting hot either! Am I looking at a faulty water pump? Please HELP!

The water pump is probably 3-4 years old. As far as the tstat facing the right way it will only go in one way so I would say it is facing the right way. I am leaning toward my water pump being out since the heating line isnt getting hot like it should be
