Now that you've got the yarn cast on, it's time to knit. Like, properly knit. Basically, you do this by getting a new loop of working yarn through the loops on your LH needle and onto your RH needle. There are two ways to do this — English or Continental. It doesn't matter which way you go about it, as they both accomplish the same thing, so just use whatever's the most comfortable for you.

A quick tip: Always be sure to work your stitches on the straight part of your needle (meaning the non-pointed part), as opposed to the tips. Your knitting will be more even this way, so it'll look better, and, as an added bonus, it'll be easier for you to work with.

A quick note: The simplest knitting stitch pattern is called garter stitch, which is made by knitting every row. Even though it seems rather bulky, it isn't always. A fine, thin yarn knit can be used to knit something in a delicate lacy garter stitch.

The Knit Stitch (in the English method)

With the working yarn in your right hand and at the back of your work, insert your RH needle into the front leg of the first loop on your LH needle. (The tips of your needles should be crossed like an X.) Wrap your working yarn, back to front, onto your right needle, and pull through the loop. This should transfer your new loop onto your RH needle.

The Knit Stitch (in the Continental method)

With the working yarn in your left hand and at the back of your work, insert your RH needle into the front leg of the first loop on your LH needle. (The tips of your needles should cross like an X.) Position the working yarn between the needles, then take the tip of the RH needle around the back of the working yarn and pull it and the yarn through the loop. This should transfer your new loop onto your RH needle.
