I'm a HUGE fan of Team Liquids website and it has some very useful information such as build orders and notes on how to control them - I highly recommend giving it a look over -

I am also currently a high level plat Protoss player; and am currently getting coached by a professional Sc2 Protoss player so I can answer almost any question either through what he has taught me or I will just ask him.
