SCV rush! Heh... it's odd but I made it to Gold in 2 or 3 leagues without ever realizing the "attack + click" function. I always focus fired by right mouse clicking.
I like trance because it's mostly melodic so it affects your subconscious mind 100x more than your conscious mind. By the time the game starts, You're zoned in and completely concentrated. Obviously the danger is a slow song comes on when they're attacking you.
Pandora and SC2 make great friends.
