Here are some sites that might help you with SDL and OGL coding.
Most of them have tutorials with detailed walkthroughs and sample code .. all you need
Cone3D Programming - SDL, OpenGL and C++ Tutorials
Lazy Foo' Productions
Anyways if you want really easy tools, go here:
3d game maker studio is a little more technical. You can download it from any major torrent site. It takes a little getting used to though.
Other than that, I would suggest just doing your own research. I've had teachers who think they know what the game industry is like, only to have another teacher completely contradict them. Independent research is the best way to go. I suggest looking at the sites everyone has already mentioned, gamedev.net is great, and branching out from there.
