Canon is not consistent with these ideas.  IIRC, Harry did not learn 
to Stun until GoF.  He also could not levitate Black into the lake 
because they were in the Shrieking Shack, which is a substantial 
distance from the lake on the Hogwarts grounds.

Had Harry known the Stunning spell in PoA, he could have Stunned 
Peter Pettigrew rather than disarm him, thereby preventing Peter's 
escape.
