It is SolidWorks or SOLIDWORKS (one word) and AutoCAD or AUTOCAD (one word).
(It bothers me when someone sends me a resume for a position and they have not paid attention to this.)
These are registered trademark names that appear on your screen every time you start the software.

There is very very little difference between Inventor and SolidWorks.
What version of Inventor are you using?
TFI CAD Tips is a good resource, but there is so little difference - any time you run into an issue, simply post your question here (don't beat your keyboard in frustration) and someone will answer it usually within minutes with the Inventor equivalent technique.
If you are ready to get deeper into the program - I might suggest this book.
There are also a ton of free white papers and recordings at Autodesk University.
I recommend starting with a Tips and Tricks class.
