Hi DrEddieS,
If you are wanting to upload a theme, then you will have to download the theme to your desktop if it's a premium or free theme NOT on the WordPress Repository.

Once you have the theme on your desktop make sure to open the zip to make insure that a bunch of other files weren't compressed along with the theme. If once unzipped you see only .php files and some folders then you're good to go.

You want to go to Appearance > Themes in your admin and click the Add New button at the top. Look for the Upload Theme link. Then upload the zipped file of the theme. It will now appear in your themes collection.

Then you can follow the steps that Jason C Levine gave you.

You can also search the WordPress Repository for a free theme. Just click on any of the ones displaying or search for one along the lines of what you're looking for.
