Michael,
Congratulations on being home.  I know what the middle of the night pain spikes are like -- I remember them well.  I just passed the two year mark on July 1.
I was lucky not to need radiation or chemo so I can't give you advice on that decision, but good luck.  I know you'll hear from a lot of people here who can give you direction.
Barb
PS  The lodge looks beautiful.
