I thought it is very easy to switch library name for all the standard cells in the Virtuoso layout editor (inside icfb). Click on edit->search, then, in the pop-up form, search for all the inst with "currentLibName", click on apply, all the inst satisfy the criteria will be selected. Afther this, in the bottom of the form, put Replace ->lib name->"yourNewLibName" and then, click on "Replace All", then, all the instance will switch to "yourNewLibName".
I don't know how to control the reference library when GDS into icfb. I usually use DEF to transfer data from Encounter to icfb, which could allow you specify the reference library list (first choice, second choice, ...)
