Yes, we do most pitching drills with the feet at 45-55 and parallel (to one another).
I'd dump the Ts and Ks and wrist snaps. I'll admit we used to do them, but that was before I researched more about the pitch and mechanics and such.
There are other, better, introductions to pitching. The T especially, I see taught with the ball pointing down. In a proper pitch, at that position the ball points up. The traditional T drill is exactly opposite of what you want.
