I would recommend not to worry about male at this point but focus on females, I would recommend at least 2 (never put all your eggs in the same basket), once the female are about 1 / 1.5 get a male, by that time it will not be long before your female will be ready and you be able to buy more genes for the money compare to buying a male at the same time than your female.
As for what to get, it's up to you check World of Ball Pythons to see what's out there and what is possible and pick what YOU like best, don't let other people's taste dictate what YOU have in your collection because ultimately, YOU will be caring for them for years to come.
