Mic close to the source and use post wizardry
This gives you the most control.
I seem to remember mention being made on one of the "The Social Network" special features a scene in a club in which they recorded the dialogue, ambient noise, and music all live and at authentic levels.
they showed the bar scenes where all the actors are pretend party and talk loudly but in reality are mouthing or whispering to maintain quiet on the set for the soundies.

That's kind of the way you have to do it, unless you're feeling brave or experimental..
(which now that I think about it - using strictly on set sound sounds like an interesting way to make a movie.. )
One of the things that many DIY filmmakers don't do is spend a lot of time listening. And not just listening to films, but listening to the real world. As I opine often, we in the film biz have chosen a profession where we attempt to create believable artificial realities that quite often have nothing to do with actual reality. But our artificial creations have to be rooted in "real" reality in order for our enhancements to induce the proper emotional response in our audience.
Would a 2 mic solution offer any help ? One close and one afar and you can blend, mix, tweak and match between 2 tracks ?
