How do I upload my template

Okay... I'm not a newbie to wordpress by any stretch, but am not an expert either. I recently purchased a url from GoDaddy (along with their managed wordpress hosting), and now found you amazing "Fest" template so I purchased it.
The question - how do I upload my template to begin customizing it for my event? There are 3 separate files with no clear call-out to choose as my file. Please help!

Thank you

Regarding the rest files package - it contains PSD (photoshop source files)
