Whe installing a new fiberglass shover/tub combo, do you first sheetrock around it, or do you fasten the unit to the studs directly?

Most contractors will use a cement backer board. This is water proof and will help eliminate any leading problems. It's always best to provide a smooth flat surface for the tub and walls. You'll be much happier with the end result.

Lasco tub installation

The question has not been answered yet. The question is: does the wall board (1/2" cement board by itself or 1/2" or 1/4" water resistant sheet rock with 1/4" cement board overlay) go all the way to the floor before the tub is installed or does the tub go in first with the wall board brought down into tile dam.

I believe it is optional, but since it is less work, it seem preferrable not to bring the wall board down to the floor behind the tub. I've seen bathroom repair books that say to bring the wall board all the way to the floor behind the tub but the Lasco installation instructions at Home Depot's website here
show a drawing without any wall baord behind the tub where there is no tile.

Tub goes in first. No sheetrock. 1/4" lattice on stud edges. 1/2" cbu down to about 1/4" of tub out turn and over the vertical lip.
