PushPulling

Am I missing something? Should I be able to push pull faces orthogonal to themselves with ease like in sketchup? Currently I'm relying on the scale tool if I want to make something longer. I know I can use extrude but that really isn't just elongating geometry - it litterally adds new geometry. How can I move a face back if i've decided that it is too far out?

Have a missed a basic basic tutorial? Perhaps a MOI tut for dummys
