Check the FG, to make sure the fermentation is finished before you rack.
When you rack, you want to siphon very quietly, to prevent aeration. Oxygen at this point will ruin the beer. I like to make sure the tip of my tubing is in the very bottom of the receiving carboy, and at a bit of an angle laying in the bottom, so it doesn't splash at all. You want the tubing to be long enough so you don't have any splashing.
