Download winarar
Download Filezilla
Make sure you have a Database on your site, make one if you haven't already.
Use winrar to unzip the folder within.
Open the folder and Filezilla.
Once you have both open, take all of the files inside the folder and drag them into the area "public_html" on filezilla.

This should work for just about all hosts.

If you'd like, make another site on the same host to use as a test site, for when uploading so you can see what it looks like. It doesn't have to have a pretty name, since it won't be used for anything other than testing.
