Not sure if you already know this, but you need to set a Mathematica 
WinXP environment variable to top level path of your separate 3rd party 
add-ons path. EG,

MATHEMATICA_USERBASE=D:\YourDesiredPath\Mathematica

This can be done under the WinXP "System Properties->Advanced" tab, then 
look at the bottom for the "Environment Variables" button. You'll need 
to restart Mathemetica after applying this new variable.

With this set, Mathematica will search for 3rd-party packages under the 
the path:

D:\YourDesiredPath\Mathematica\Applications

Also, if you want a package autoloaded, add the subdirectory "Autoload", eg:

D:\YourDesiredPath\Mathematica\Autoload

Hope this helps.

Also, your personalized preferences should get stored under 
D:\YourDesiredPath\Mathematica.

BTW, I believe WRI's doc's on this are very poorly organized. You can't 
find all this info in one convenient place.
