Ginge, my advice re cat choosing is to chose based on their personality, rather than colour etc. You can get a feel for them by watching the litter interact. You don't want one that's bossy or dominant, or hyperactive, nor one that's too shy. One that sits in their own space but communicates with you is the one to get, kwim?

Other thing I would say as an owner of a lovely and very sociable cat, is you need to train them when they're young...people tend to think cats don't need training but they need to be told (using hte same body language the mummy cat would) when they're outta line.

BTW I wouldn't ever choose a male cat just because sometimes the spraying can get out of hand.
