I was fortunate to get SolidWorks training through my company. Since then I have used Mechanical Desktop, ProE and Inventor with some help from my co-workers. I did take a Unigraphics tutorial.
ProE takes the most mouse clicks.
Unigraphics is used by very few Companies.
SolidWorks seems to be the most user friendly.
Inventor isn't as friendly as SolidWorks. (But I've only been on it for 2.5 weeks.)
Is the company asking you to learn it? or is this on your own?

AUTODESK INVENTO ESSENTIAL PLUS by Thompson Delmar Learning is a good book. This is used by the college I am currently attending. It also contains a CD with example and tutorial materials. This will take you from the basics to advanced features. The inventor program also has online tutorials built in.
AUTODESK INVENTOR - I had to teach myself this program this year. It has a steep learning curve. The tutorials which are available from the Help menu or the Autodesk site are what I found most valuable.
I was able to model and animate a mechanism in a few weeks. AutoCAD experience was irrelevant.
It is an excellent tool and worth the frustration you are going through. Once you get the hang of it, it will save you much effort.
