I've heard these cars mostly had ABS, and they are full sizes, so would I be correct in assuming they use the JA2/JM4 (ABS) pattern of 5x115mm? Also, what is the usual offset?

Yes that car has ABS, and the pattern is 5x115mm. I've seen varyingoffsets, from 35-45.

The car currently has steels. I wanted to put on these 16x8 crosslaces I got off of a '95 Grand Prix. Think they'll fit?

Doesn't work. The Deville has a +55 offset, the Grand Prix wheels have a +38 offset. There was some significant rubbing in the rear. A damn shame too, the car looked really good with those wheels.
