Rename Mu Support System

hi there

I'm wanting to rename the support system and want to know what I can change without breaking the plugin.

I've named it in the Support System Settings.

I'm also wanting to change it so when the user is in the support system page the page title isn't MU Support System and the url isn't wp-admin/admin.php?page=incsub_support

My members get confused with Wordpress - seeing incsub_support & MU Support System is gonna make their heads implode!
