Decent beginner's workout routine. You should also check out the book
Starting Strength for some more info and ideas.
But like psalm said, do your own research and find out what works best for you.
Losing 100+ pounds is nice, but you'll still be flabby if you don't build muscle (depending upon skin elasticity and body type).
