You need mod_rewrite installed and working and the server able to read the htaccess file.

Bet bet, ask your web host's support.

The post url on front end is hte same on the back end -- I checked the permalinks and they seem ok?

"I have been have nothing but problems with thumbnails and the upload folder,"

If you have a theme using the timthumb script, then yes - you will have problems.

Contact the theme author, show them this:

Andrea, you have always been of great help - I was on your site and I learned that you consult for$45 per hr -- i wonder if that applies same for on-site help? --- next week if you have time i'd love to pick you up on one hour or so....
as of the thumbnails - its been a nightmare for me - i basically did everything from changing permission to permalinks to even changing core code -- and still no luck.

Hit me up on the contact form at ronandandrea.com. :)

I get an error 404 when I view my post. The error is wrapped around the theme. Its NOT a browser error.
