A few things to check out.
I started 3 days ago, it's quite easy to get the hang of for more basic worlds, I promise. I found this seriously helpful...

It's a guide to everything you need to know, all be it a basic guide, It's by EA.
I also found the Creators live chat here a very useful place to visit, ( click on discussion at top left of page, then live chat, then creators chat). The people there have helped me out a lot, with a few issues I ran into.
Also if you run into any problems, have a nosey through the CAW forums here, most issues have a thread, that's worth checking out if you need help.
From one n00b to another, good luck and have fun XD
