Looking for a program to simplify the layout and functions for a Web browser toolbar. Something that can be easily customized to ad Facebook, Twitter, RSS links. Have some commercial clients requesting the possibility of adding this download to there website for frequent visitors.

Conduit comes to mind for me, I didn't "use" it persay, but I did check it out a few years ago and recall it being pretty customizable. Try this google search for Customizable Toolbars:
