Removing unneeded programs

We are getting ready to upgrade v4r5 to v5r2.
I want to clean things up on our current system prior
to the upgrade and possibly remove unneeded
programs. Here is a list of all of our installed
programs.  Any thoughts on which of these might
be candidates for removal?  I'm thinking that I
won't need the dictionaries once the OV/400
stuff is gone and wonder about needing
all the Java developer kits.
