If you're just starting out with free weights, an olympic weight set (2nd link) would probably be your best option. You'd quickly outgrow the amount of weight in the first link with deadlifts. A set around 200 lb is a good starting point, and you can always buy more weights when you need them. Try to get some 2.5 lb plates so that you can make 5 lb increases. The olympic barbells in these sets aren't the best quality, but I didn't notice any bending in my cheaper bar until about 300 lb.
Stronglifts is a good program, and there's a lot of free, useful information on its website. Make sure to check out the articles and videos on form. Best of luck.
