Yes, you can use latex paint over oil-based paint. First, scuff down the surface of the oil paint layer for improved stickability. This has less to do with the initial coat being oil-based than the fact that this is a paint-over-paint project.
You have to use acrylics and latex paint on foam. Oil base can eat the foam. I covered my foam with Sculptimold plaster. Some folks just paint their foam directly. Cheap craft paint from Wal Mart works OK. If you have a big area, you can get a gallon of base color mixed up at Home Depot or such.
