By now you have signed up for Cycle Oregon and are back on the bike. I do have a bit of advice, after having my knee replaced last October, and I believe I did too much too soon, especially weight training. I have since quit that and am just cycling. I would spin, keep cadence high, and skip the steep hills. I am 8 months out, and am only now easing into steeper hills. I still have pain, swelling, and an annoying click under the knee cap. Hopefully you are doing better.
