Drop.SC

To add on to what others have said, providing uploads would be great. I personally find drop.sc to be the best place to upload your replays. 

A piece of general advice is that one of your biggest advantages in the early game as Protoss is the mobility of your stalkers. Before stim comes out (or concussive shell marauders) you can totally control the map (and hence see what's coming) and simply kite marines all day.
