Removing certain features?

[zoe]

There are some features that I'm not planning to use, and would like to remove from my site (mostly for organization issues but for security issues as well!). The features are:
-Promocodes
-User being able to change the site's theme
-Links to skype, AOL, mail, etc on an user's profile
-Breeding
-Pet spotlight
-Shoutbox/visitor message
-Making friend list public

This is a very long list, so I'd be fine with just a general explanation.

Thank you!
