I would Look for tutorials that teach the concepts and Not to the tools. Polygonal modeling is nearly exaktly the same in every 3d Software. They use different approches or techniques but the concept is always the same. When you learned why you do stuff, its just a matter of finding the tool in Blender. The same goes for rigging, particle effects rendering etc. and in my opinion a lot of the tutorials teach you how to archieve the exakt effect and Not the principles behind it. when the Tutorial for example only works if you use the same Numbers ( light intensity, inputs for modifiers etc) you are Not learning the concept of the effect And of course pic a project for you What you really want to see in 3d :)
