Yeah Dorf, to re-iterate: steroids bad. In fact I'll go one better and say to avoid most any suppliment (other than your average multi-vitamin and plain-jane protein shakes) for your first year of training. The reason I say this is because you don't yet have a barometer for your well being.
By which I mean, you are going to be (hopefully) changing your eating lifestyle, working out regularly (and let me say from one husband to another, you are going to love to watch her get fit. That first time she bends over get a weight and you see hamstrings? Heh, just remember, gyms take a dim view on PDA on the floor

) Anyways, my point is you are going to be stressing your body pretty hard already and it is going to retaliate in the predictable manner, you don't need say the bloat of creatine loading to add insult to injury right away.
A couple of books that were great sources of information for me and my wife when we first started were The Complete Idiot's Guide to Weightlifting which breaks down workouts, diet, and rest into the easiest to understand form. And for a little later down the road (and please no one flame me for this one) but I found Arnold's Encyclopedia of Bodybuilding to be indespensable. Once you get around him talking about himself, he's got quite a few gems of training knowledge that deserves to be brought back to date.
