Library vs Environment?

Question

I've added (by hand) my Roland JV-1010 synth module to the environment in a project. I can import that into another project (though it's a little tedious, importing one layer of the environment from the other project). But the patches for that instrument don't show up in the Library. What shows up in the Library at this point is several versions of the JV1010 I've experimented with, and the "patches" column doesn't let me choose anything useful--I have to go back into the Environment and select patches there.
Two questions:
1. How do I erase something from the Library? Those old versions aren't helping, but I can't find a Delete item anywhere.
2. Is there any way to get the Library's patch list to show what's really in the instrument (according to its representation in the Environment)? And is there any way to change banks and select patches by name, without going back into the Environment over and over?
I hope this makes sense, and I hope somebody can help me make sense of this. Where does the Library really live?

In relation to having multiple libraries, how do you attach all of the field level scripting for an individual service?
Do you have an automated attach routine or do you manually attach scripting?
I have been able to come up with a method to automatically attach a script library associated only with a particular service, but I'm still working on trying to update our automated attach routine to create/attach the field level functions.  Any insight someone would have in this area would be
