Hm... I see, the stats from elo show that you haven't noob bashed or point traded for around 2 weeks. Good enough for now I guess.
There are a horde of russian strategies in strategy central, use the search button or the comprehensive guides. Kivlov is the main russian expert here, you can ask him any specific questions in the ask & tell thread (mentor & mentee forum).
For microing, use the search button, I believe Moshe Levi made a thread compiling most of the microing tips. Tips include:
Hit & Run - Shooting, moving back, shooting again
Herding - Get your villagers on the other side of a hunt and shoot
TC Hopping - Defensive Micro, quickly jump your villagers out via hotkeys, let them shoot, then jump them back in via hotkeys so that the tc can shoot. Rinse and Repeat.
"Villager Walking" - If a villager is going from one side of the tc to the other, garrison him in the tc and then un-garrison him, saves a couple seconds of walking
