Joe, I don't think you will find a better forum around for learning SketchUp.
We also have a Woodworking Forum in our Special Interests section which will probably be very suitable for you.
http://www.sketchucation.com/forums/scf/viewforum.php?f=156
You will need to subscribe to see it. Just go to your User Control Panel (UCP link, top left of screen) choose the Usergroups tab and select the forums which interest you. These will then show in the Special Interests section.
