Regarding conditioning, I think you'll be fine. I worried about the same thing this fall/winter, as a new job sapped all of my time and I had basically no time to ride. My fall/winter was spent trying to get 30 minutes every other day on a spin bike at the gym, and often failing to even get that in. I found that when I got back on the bike in the late winter/early fall after probably 4 months of nothing it wasn't bad. Sure, my first 100 mile week was pretty tough and painful, but it wasn't bad. Within a month (or so) of being back I did my first metric century with little issues. I rebounded VERY fast and am now back to the best shape I've been in.

Summary, a month or so off the bike shouldn't do too much to you. Ease back into it, and I agree that conditioning loss will be minor compared to the risk of damaging yourself further.
