I used to upload zip files and unzip it before i found out that my control panel could do it. zJunior I think this can help you.But bear in mind that when unzipping, you need to use the CHMOD (755 or 644) option. Else you won't be able to modify nor to delete your unzipped files.
Unfortunately i'm not home, I could have send you the script I used.
But you can have a look here
