I generally parameterize the voltages, e.g. "vdd", so any sim that I (or any other designer) am running in the same library can use the parameterized name to handle arbitrary supply voltages. For the a2d elements, you could do something like "0.3*vdd" and "0.7*vdd" for those thresholds.
yes this approach is how it should work, but in the past i've found it rather temperamental as to whether the analogLib IE accepted the override... perhaps this issue has been solved within spectreVerilog since I last used it...
