don't confuse soundproofing with having a good acoustic environment. You could have a perfectly soundproofed room but it could still be a lousy recording environment.

I'm going to disagree with Jim here, I think environment is the most important thing. You could have the best mic, best recorder, best everything in the world but it can only ever be as good as your source. If your recording environment is poor your microphone recordings will reflect that and your monitored mixes will suffer too (the best monitors in the world will not compensate for bad acoustics). I accept that all the things mentioned are important but if I were starting from scratch I would be mindful of getting the room as good as I could.
