How and where do I go to learn how to make a 3D game with DirectX and c++?
First question, have you at least learned the basics of C++ with console applications?
As Avilius said, you have to learn the very basics before moving on to graphics.
You guys don't need to worry about what I already know. You need to worry about answering the actual question.

make sure you spend enough time in making your basics (foundation) strong enough to take complex ideas as well
best of luck
