Bowflex isn't really different than standard weight lifting and I assume they gave you something that shows you different exercises and how to use your bowflex?
One thing you should consider is working towards muscle failure which will give you the best benefit of weight lifting. A standard routine is 3 sets of 12-15 reps per exercise. I'd recommend making the weight such that getting to 15 is somewhat difficult. I'd also recommend resting your muscles at least a day between workouts. That doesn't mean you can't use your bowflex every day but you could work a couple different muscle groups one day, then work different muscle groups another day, then work yet other muscles the third day.
A couple good sites that could help you are:
They don't mention bowflex but they do show exercise routines as well as gym type exercises that can be replicated on the bowflex.
