There are a number of good books available on Amazon on Inventor as well as a number of video's on YouTube.com that are really good. You might consider taking some formal classes near you or looking at AU in Las Vegas every fall (end of November - beginning of December) for classes in the different aspects of Inventor.

There should be resellers in your area that offer training and classes as well.
