First breeding pair. What else to get?

Hi! I have acquired a breeding pair of corn snakes, one is normal in colour (male) and I was told the other is a ghost (female).

I was planning to breed corns about 10 years ago but never properly got started, so I know a little bit about the morphs and genetics but find it all very confusing.

I know this pair have bred before and produced normals and some anerys. Does this tell me anything about their hets?

What other morph could I get to produce some interesting babies?

Thank you!
