When you first release the clutch, the friction between the clutch itself and your engine flywheel will try to slow the other down. Let the revs drop too far, you'll kill the engine. A gentile touch on the gas can help this, keeping the engine revs up to a certain level enough to get the car moving and allow you to release the clutch the whole way.
Once the car is moving, shifting is less complicated. Once you get high enough in the RPM range, (you'll know when you want to shift), depress the clutch the whole way, and move the shifter (be sure to hit the gear you want, a 1st to 3rd shift can suck while moving slow) to that gear. Get back lightley on the gas and let the clutch up.
So your moving, great, but what about stopping? To slow down, I find it best to depress the clutch, give the engine some gas and, while moving the shifter into a lower gear, let the clutch up. This lets you do whats called "engine braking", or slow down without touching your brakes. Because your in a lower gear, the transmission won't spin as much power to the wheels, so you slow down. When you get to the light, stop sign, or whatever, depress the clutch again and then use your brakes. Then it's time to start all over again.
I hope this helps, I'm envious of you. I'd kill to drive a manual, but I'm stuck with this little 4 speed auto that I can shift like a single footed standard transmission. I've only driven manual once, but it was great.
Have fun dude.
