Starting production

I've been DJing for a few years now and i'm finally about to start buying some production gear. I know you've probably seen this type of thread a million times now but your help would be appreciated.

I was thinking of getting a macbook and putting Reason on it to start off with and using a midi controller. I also have a copy of Ableton live LE somewhere that should give me a good idea of how the whole subject works, maybe thinking about buying the full version later. I was also wondering what type of soundcard or interface would be best, and if I would need a small mixer or not. I was going to get the M-audio bx8a monitors as they sound great.

Budget isn't too much of a problem as i've been saving for a good while and I think the gear is most definitely worth the money.

Please tell me your thoughts and any other things that you would recommend to me.

Cheers
