What pattern are you working on? That will help us help you.
Are you casting on stitches after the stitches you've bound off? If so, you might try the knitting cast-on, so you don't have ladders (or gaps) between the old stitches and the new. You can see a video here: http://www.knittinghelp.com/videos/cast-on
(Scroll down to find it.) At least, I *think* you can use the knitted cast-on in conjunction with bound off stitches. If not, someone here will be along shortly to correct me!
Also, when you knit in the round, you are knitting a tube, so you will need either a circular needle (if you have one short enough for your stitches to fit around it) or DPNs. Once you get all the way around the circle (or tube), insert a stitch marker after the last st, and then knit or purl (depending on your pattern stitch) the first stitch to "close the ring." You can also pick up and knit in the first couple of joining stitches using your working yarn as well as the tail end of your yarn. The videos for working in the round on this site show you how to do that!
