Yeah, pick a really cool female to grow with the other one. Buy the male when you're just about to breed.
There's a smorgasbord of morph female babies that you could choose from to make some great combos. And who knows what males will be available when they're grown and ready. Yellowbelly complexes make some great things. Blue Eyed Lucy complex has a lot of options, too. Then there are the pattern morphs, like pinstripes and spiders. Then there's the idea of going for a super. Like a super fire, or super disco, super yellowbelly (ivory), super orange dream, super paint, super mojave, and so on...so on...so on... Maybe look at one of those that pairs well with pastel (almost all morphs pair well with pastel), and consider going for a super.
Welcome to the addiction, and happy herping!
