I highly recommend the video tutorials on the blender 3d website.  Many of them are for older versions (some for *very* old versions), which does mean the things they use in the buttons window may have moved (e.g. the subdivision surfaces).  If you run across something like that, check out the other panels in the buttons window and the other tabs, if you still can't find it ask here :)
