N.b this is more a continuation of my reply to stopngo
Quite. Also, when dealing with any unit always think what the logical follow up will be - if he's going heavy hellbat/hellion, he's going to be walking into a mech build. Hence the fast mutas - mech is a) slow bar hellions which can't shoot up and b) stupid-weak vs air until the thor/viking count gets high enough. If he's going for a few - just zap them with queens; he's only after throwing you off balance. Building a handful of early roaches and making a move out can indicate you're going for a 2-base all in rather than a 3 base roach max, if his scouting's not perfect he's likely to pull back to defend at that point = you're free to get your third and regain map control.
Disclaimer: I main protoss, but I used to play terran enough to have a pretty good idea what their weaknesses vs Zerg are...
