So I was just seeing if anyone had any tips for a Protoss player? I've been watching some videos online, but I still haven't been doing well.
One of my favorite strategies was the 2 gate goon. Forgo even making lots, and just rush for 2 gates and pylon. You should have 4-6 goons out in under a few minutes. They're very powerful against Terran who rush vultures and are great in general against zerg (although you WILL need some lots to soak up the zerglings and especially the cracklings).
Another very awesome build is the 2 gate dark templar rush. It takes a few minutes, which is why the forge is actually the first building you should drop after your pylon, which you drop in the choke, and then you put a photon cannon down at the choke too. When you get your first 2 temps, you can actually place them in the ramp spaced properly on hold and no one can get past them. An enemy will try clicking up there, they will go up, then half of them will explode. Use them to keep people out of your base while you attack with 4 dark templars. The game should be over quickly if you take out their mineral line and defenses.
The 2 gate dt rush is awesome because you have lots of tech options to work with. I've actually won with my original DT group in a Terran vs Protoss (me) game using good use of speedlots and max ranged goons. I then used my dropships to drop in my dts while my opponent was occupied, then ordered them to kill all the detectors and comsat stations. By the time he realized what was up and got tanks and goliaths up there, all of the detectors where dead and all of his mineral line. He GG'd and surrendered.
