ok.. so is my best bet to leave that listing there and remove all but one item and then relist with the better title?

I find a change of title is often the spark needed to start a sales run.  It is definitely worth a try so I would agree that if you reduce the stock available on the old listing and give the new title a go, it should not take long to build up its own sales record (if not, it is a cheap lesson in marketing).]:)
