there are loads of free video tutorials here at the COW ... many are at a beginner level ...
http://library.creativecow.net/video-tutorials/adobeaftereffects
also look at non-video tutorials, there are loads out there and often they are just as good as any video tutorial ...
and I'm sure if you google "After Effects tutorials" you will be swamped with thousands of online tutorials ...
good luck
