Now that I'm off my soapbox, I'll offer a thought on mic and cans, as you requested
I like the "vintage" tone of my MXL V69ME but might recommend something different if it's the only mic you'll use. If your budget is under $300, both Audio-Technica and Rode make mics that sound good. I've personally used the Rode NT-1A and the AT4033 or AT4040 (wasn't mine, can't remember) but they both sounded noticeably better than my first mic, an MXL990. For recording acoustic guitar, all of my condensers sound better than my SM57. If you get a mid-level LDC, it will most likely be able to record acoustic guitars very well, so you may be able to "save" a couple bucks by just getting a good LDC instead of two lesser mics.
Cans, I use Sony MDR7506 and they sound great.
