You upload them via ftp to the themes directory in your Wordpress install. The next time you start Wordpress or go to the presentation section it will be made available to you however this had to be a distribution of Wordpress you install on your own server (not necessarily one you own but rent from a hosting service). If you are just using the free Wordpress blog service at Wordpress.com you can only use what they give you but if you have your own site (not a free service) you can customize a lot more, etc.
