Hi, Chris.
Welcome to the board. You definitely came to the right place. This list is a gold mine of advice. Actually, it seems you already got lots of solid advice.
I would just mention one issue. Overall, it's definitely wonderful to exercise. However, heavy exercise can possibly throw off some of your test results. In trying to keep my BP and weight down, I increased my exercise significantly (well, I mean, relatively for me)--and ended up dumping protein into my urine, which nearly caused the medical director of my transplant center to disqualify. Although I respect her for trying to protect me from myself, let's just say that I could have done without the resulting delay and multiple rounds of re-tests.
The testing and evaluation process can be long and stressful. I recommend regarding it as more marathon than sprint. Also, as my own experience taught me several times, one or two sets of "off" test results doesn't necessary mean the end of the world.
There is a wide range of patient experiences after donation. I was home within 72 hours of the surgery, and was back at work 3 weeks post-surgery. I had no major digestion-type issues, no terrible pain, no major tiredness (after the first few days), and have been doing fine since. I did find that going over bumps on the bus hurt quite a bit, for a month or two, and I took cabs to work for about two months (I don't drive, and have a long commute on mass transit; I wasn't up to standing for 1-2 hours each way). Beyond that, think about NOT sleeping on the "surgical side" for a month or two after surgery.
Meanwhile, do as much research as you can, and be organized. Keep track of your various test results, go into appointments with the docs with questions already written down, read as much as you can, etc., etc.
Good luck!
