Solved Working with a lot / sorting a lot of Clips

OK, I've got a background recording for a choir loaded with thematic lines, little runs and stuff.  In the process of "maintaining a reference in the beginnig, I have a lot of parts recorded that I really don't need, and some are on the same track that I do need.
 
I've worked with a lot of video, and If this was and NLE, I would just slice and dice, open up a new timeline and start lining up clips from various bins ( and timelines ).
 
Workflow???
 
Will the same approach work here.  I have way too much material and duplicate parts that I need to pick through.
Ideally, I would find the themes i need and just drop them on a timeline where i need to ( copay and paste original)  leaving the rest of the stuff on an old timeline to just save if i needed it.
 
Already I see I can't just open up a new X3 "program" and move back and forth..  I have figured out how to keep two sets of "saved files" in the same open program ( with three monitors )
 
Something I discovered - after it was too late,  I had an issue of transferring some files from my laptop to my workstation and doing a lot of work only to find out that my reference track that I made into a beat track to sync a fit to improv ( thanks for that advise )... anyway.. when i moved my files from the laptop up top my studio,  I realized that things were a little squirrely.  Turns out that my tempo track reference ( where ever that lies ) was no longer running things and it was a straight tempo. ( thus my audio track that I was transcribing from ended up being enough out of sync to drive me crazy.
 
 
Can I drag stuff ( or copy paste ) from time line to time line - Am i missing assets that I need.
 
 What really throws me is the track that I copy and paste keeps the original track name.  Life would be nice if there was some attributes window ( that I have not found yet ) to rename source material as needed to relate to the new track.
 
I know I'm asking a lot of stuff  in the last several days and I apologize for not being able to find solutions my own as fast as I find problems.
 
 I guess it's obvious as to who just fired up the program to do something beyond elementary after never working with it.
 
If it wasn't for you (all) and the Scott Garrigus X3 book I'd be dead in the water. 
 
Thanks again.
