Simplest: Zoom recorder with external mics. You don't have to fuss with interfaces, computer noise, etc, etc. People have released CDs made this way that sound totally professional.
I'm not sure what Behringer mics you have, but that's the only brand I've seen where someone was posting here with pretty bad results, and it turned out to be the mics. I'd get something better (not necessarily more expensive) for mics.
Reaper for editing and mixing should do the job.
If you haven't seen the video I made for Acoustic Guitar Magazine of the entire process using a Zoom and a pair of AT2020s, with Logic for mixing, it might be helpful.
