Stuck with Key bindings

Hello there! 

I have had SC2 since release but I do not play so seriusly. At last, I manage to improve a bit seeing some casters (most day9^^) and playing more often. I belive than my knowledge of this game is not so bad and I know how to react, build orders ...

The big problem is than I am really mouse dependant, and I am a Zerg player (that is a great issue!!!).

I am not trying to be a TOP 1 master, but I am always trying to improve , I will thanks anyone than can guide me to find methos/ways/maps to improve the use of key bindings!!!

I know I have a lot more issues in my gameplay but like Day9 say at #419 "Fixing 1 thing at a time" is the right way.
