About the slow roach vs void situation:
I might have taken for granted that everybody has experience killing slow roaches off creep with void rays. I love opening with zealot+void pressure, so I do this micro almost every PvZ.
What you do is you select your voids, target fire them on the leading roach, and then shift click each roach in order from the front to the back. Voids move at the same speed as slow roaches off creep, and they shoot while moving, so any roach that gets target fired will be killed (and quickly). The trick is understanding that the void won't move while shooting until its target is 6 range away, and it can't acquire new targets that are greater than 6 range away, so if you let the void select its own target, it will naturally pick up the roach at the back of the pack, and when that roach dies, the void won't be able to get in range of any new roaches. But if you target fire them in order from from front to back, the void will dispatch the leading roach, then pick up the second roach, then the third, and so on while always staying 6 range from the front of the roach pack.
A charged void ray can kill a roach in 6 game seconds. If Z wants to attack P with slow roaches on a moderately large map (say 60 second rush distance at slow roach speed), one void ray can kill 10 of the roaches before they reach the Protoss base. In other words, the attack will suck. If Z waits for roach speed, one void might be able to kill the lead roach and do a little damage to the back roach.

FYI the Zerg can counter this with some simple micro of his own by microing away the targeted Roach away from the pack so that the Void Ray cannot "lock-on" any other targets.
