Hi Alan,
Good investment. Camtasia is a great powerful tool.
I used it for a couple of years before buying Screenflow ( a Mac program) after I finally gave in to my geeky brother who kept on my back to get a Mac computer.
I'll have to say I'm in love again (but don't tell my wife that).
You have probably already found your way to this page below that has a ton of Camtasia 5 video tutorials by Tech Smith.

I suggest you get you head down and watch a heap of them and start playing around with the basic functions.
It's also good to look around at other online screen video recordings and make a note of what you like and what you don' t like so you end up with your own unique style.
Have fun.
Anthony
