The fluxbox site, well worth looking at for apps and documentation.
http://fluxbox.sourceforge.net/
Fbdesk will allow you to have icons, wmdrawer is nice if you want an icon drawer. Rox filer can set up an icon panel. to give you a couple of options.
Fluxconf will give you a GUI for configuration, if you feel you want one.
Once you start playing with it you will find that all the configuration scripts are fairly easy to follow.
Have fun
