Autodesk Products (HELP)

Im trying to learn how to do 3D projects. Like, design cartoons that you may see, like a Disney Pixar look. And i want to design houses, inside and out, cars, and more. For 3D movies, or short clips. Animate it and everything. You know…
So, for all the users out there, whats the best programs to make this happen? Can i just use Autodesk products? If so, whats the best one to use. Or should i use multiple.

AutoCad
3ds Max
AutoDesk Impression
Maya

AutoCad VIZ 2008
AutoCAD Architecture 2008

With these programs you have to deal with math and grids. I want to know how to make it happen. I need any step-by-step lessons. If anyone has em’ let me know, PLEASE. If you go to http://usa.autodesk.com there is a banner that shows what you can do. It shows streets, buildings, cars, and people. I want to do that. So, if anyone has info, shoot-it-to-me. I will appreciate it.
