There is a commandline option that allows you to set the  
configuration location of uDig.  By default it is in the eclipse/udig  
installation.  For example:
udig -configuration ~/.udig

to tell udig that the configuration should be at ~/.udig.

I think Adrian addressed this one.  Another command line option is  
useful here -data.  It tells eclipse where the workspace should be.  So:

udig -data ~/udigWorkspace

Put the two together and you get:

udig -data ~/udigWorkspace -configuration ~/.udig

Hope this helps,
