New Hard Drive + New Red Hat 7.3 = New video problems

I just installed my new hard drive *yay!* and since I got a new hard drive I thought, well I like change and moving onto a new flavor of Linux wouldnt be that bad. So I installed Red Hat 7.3. Everything was going smooth got everything running. But then It came time to hook up the offical nvidia driver (from nvidia.com) and install all the OpenGL stuff for linux I ran into problems. So I went to nvidia.com and dled all the stuff (I used the NVChooser) and changed all the stuff in the XF86Config-4(yes, I checked thats the one im using) and it says when I tell to to Load "glx" and Driver "nvidia" it flickers for like 2 min then says no screen found. But if I take those out I get right into X. Any one know whats up with that? Well after that happened I tryed to set up all the devel files for OpenGL. I installed glut, libmesa, mesa, and SDL devel. When I try to compile my project it says GL/glut.h not found, I thought it was in mesa. SDL compiles fine but if you see something else I need please post a note. I need glut and SDL to fully work.

If someone could please please help me I would be very great full.

Thanks
