I have got two ways of changing your Facebook profile theme. One is using the Greasemonkey Add-on and the other using the Stylish add-on. Here is how you can change your theme using either of these two:

1)Using Greasemonkey Add-on:
First ensure you are using Firefox browser and then install the Greasemonkey Add-on.
Restart firefox and Visit this page with lots of Themes.(http://userstyles.org/styles/browse/facebook.com)
Click on the favorite theme you like and install the script.
After you load facebook.com you can view the change the Facebook theme.

2) Using Stylish Add-on:
Ensure you are using Firefox and then install the "Stylish Add-on".
Restart Firefox and repeat the process as shown in Using Greasemonkey Add-on
Apart from scripts in above listed site, you can check out these sites for other themes:
1) Some themes on Userscripts.org.
2) Facebook Fixer which enhances facebook with bigger picture, download viedeo options and more.
