How insulate over slab?

FWIW, I'd do it a bit differently:

1. 4 mil plastic with adhesive below and above.
2. Put down 2" compressible styrofoam (same as used under concrete).
3. Apply 3/4" UL over foam with adhesive.
4. Your choice of flooring.

Advantages include:

1. Less loss of height
2. Much higher R value.

I included the 4 mil plastic, but I'm not sure it's needed. The vinyl tile and it's adhesive may effectively seal the existing floor. I would guess if you put some plastic over the existing floor and don't see any condensation inside of it, you may not need it.
