119466 Simple Modification for script

I have a membership script that is perfectly working. However, I just want 2 things added to make it easy for me to install since I'll be installing on multiple sites. 1) create 1 step web installer that allows the user to enter in database details, rather then edit the php directly via ftp 2) allow admin account to edit site settings such as: change password, site name, and navigation links in member control panel Should be quick and easy for those with good php skills. Thanks.
