NeHe has 37 OpenGL tutorials and 7 OpenGL game tutorials. It is a good place to start. If you are working full time on this, you should be able to go through the tutorials fairly quickly.
OpenGL is a graphics only API. You can use Win32 API or DirectInput for input. Both are pretty easy to use.
I don''t think there is really a standard. Quake uses multiple maps for a single level, one for objects, one for lighting, one for sound. It depends how complex you are going to get. You can even invent your own file format.
MilkShape3D is a good modeler. It only costs $20US. A free one is Maya. Some people swear by it, but I don''t like it. I think it doesn''t like Windows to much.
If you goto
Wotsit, it lists a very large number of file format specs. A couple that are used in 3D games are .md3 or .x
One note, NeHe''s tutorials use keyboard input using the Windows API. This should help with your input problems.

I think the first thing I need is a 3D engine, that I also want to make myself. I plan to use OpenGL. Does OpenGL also support keyboard and mouse input? If not I think I''ll use SDL because I''ve got experience with that. Or is there a better alternative than SDL?
I''ve got no experience in OpenGL, so are there some good tutorials on how to make a simple 3D engine in it, or open source examples?
After I got this 3D engine I think I''ll need some sort of file format for maps, and the ability to make them. Are there any standards for this?
And then the hardest part I think: modeling. Maybe I''ll just use 2D sprites for this, like Wolf3D, but what do you think. Is there free and easy software to make 3D models? Animated models, even... What file format should these have?
Well, please reply, even if I never get into making the game, then at least I''ve got a general idea in how this happens, because I''m interested
