Kim,
To help tone the knee area, biking is great. Otherwise, just lowering your total body fat through careful eating and exercise (cardio and weights) will help.
With deadlifts, the lower back is working isometrically to keep your upper body stable. You are right to engage your abs when doing these to add stability to the core(instead of "sucking in your tummy" or holding it in like you do when trying to zip up a small pair of pants, you can also think of pulling in a corset--even if you've never worn one, you can imagine what that would do...kind of an "all-around" pull in of the core).
Make sure that your upper body is staying in the same position throughout the move and you are bending at the hips, not the waist. Keep your shoulders back and down and your chest out and up a bit (I like to think of the perfect deadlift position as one of those toy birds that dunks it's beak in a glass of water and then bobs up. The only movement comes at the hip, and the upper body stays in the same position throughout.)
