With regard to your first question, you could also
A) plan to move to a hospice near a facility when you are near to death
and/or
B) arrange for standby to transfer you after legal death.
Of course, there are many trade-offs involved with either. In my estimation, the most useful thing would be for you to get engaged in a local community and try to push forward on basic research and logistical issues involved, although obviously that is not an easy task.

With regard to your second question, as with everything in cryonics, this has been endlessly discussed. See a good article by Mike Dawrin on the topic here: http://chronopause.com/chronopause.com/index.php/2011/08/11/the-kurzwild-man-in-the-night/index.html
