GoDaddy Issues

Okay, I am new to wordpress and am having extreme issues. I am considering moving hosting and doing a fresh install, but would like to try to fix this if possible.

GoDaddy is my hosting provider and I am on a standard linux setup. I did the one-click WP app install and my site is up at skinnywin.com. This is not a monetized site, this is really just for a silly competition with my friends, but I do want to be able to edit the theme! However, my issues are:

1) What I FTP is not reflected in my wordpress account. I edited my sidebar.php file to remove the meta links in the default theme (the only one i can use right now – see below). The meta links are still there.
2) I have no theme editor in my design tab.
4) When I FTP new themes they do not show up in design tab (and I triple checked to ensure I did this correctly).

I have messed with the file permissions extensively and scoured the forum for anyone with the same issues and have found no luck implementing the solutions they found. I work on another wordpress.org site and love the functionality of the theme editor and ease of use, I just want to be able to get to that point!

Thanks in advance!
