Here at wordpress.com we cannot upload themes, we are limited to the themes listed under appearances > themes. Themes here are not the same as the ones you see out on the web for download. They have to be modified to work here and for security concerns, then tested in all browsers before they would be available here.
The only thing we have is the paid CSS upgrade which allows you to modify the look of the themes here, but it does not allow changing the functionality. It is also not recommended unless you have experience editing CSS since there is no official support.
Go to the FAQ’s and search for CSS for more information on the paid CSS upgrade and some suggestions on where you can learn about CSS,
