Welcome Blakjack66! You have found the true path to map enlightenment and nirvana...
I'm kind of a newbie with CC3 as well, but as has been told here by those that know... follow the tutorial in the little start-up guides. If you've never used a CAD app before, it can be a little daunting, however, if you follow the included tutorials you should get up and running fairly quickly.
I'd say DD3 is a bit tougher than CC3, but do the tutorials, get a feel for it, then visit here frequently and post your questions. In a very short time you should be well on your way to creating awesome maps.
Once you get the hang of it, its just learning the whole system overtime to expand on your mapping skills. That's my 2 cents!
