I'm always playing acoustic, so here's a few ideas I've either experienced or borrowed from someone else....sorry if I can't give proper credits, I do a lot of reading on recording acoustics....
Better Strummed Sound
-Mic 6 to 8 inches from Soundhole, too close tends to yield an unbalanced sound. I also put height just below the soundhole, slightly.
-Angle Mic toward fretboard/soundhole joint (pointing the mic directly into the soundhole will produce a more full/boomy sound...almost too much)
-moving the mic horizontally towards the bridge will get you a brighter/more treble sound. Towards the neck will mellow it out.
-Compression: 3:1 Ratio to knock down any peaks, lower threshold - squashed/tight sound, higher threshold to just limit the peaks. Either/Or
Adding a little more compression will help you get that earthy John Mellencamp/Tom Petty sound if that's what you're looking for....they also use Medium Guage strings along with a mid boost between 700 Hz and 1.2 Khz which helps to make that sound.
-Eq: to reomove Boominess: Bottom rolloff 100Hz, cut at 300 Hz, to add some silk give a little around 8 - 10 K, but it might ad noise to the track, be careful.
-Just as Axeman said, I always use 2 mics on separate channels as well to try and and get a better idea of sound, sometimes 3 tracks and include the piezzo bridge pickup.
