mmm mmm mmm! i have probs w/ most of the foods you mention. though my reactions are mostly NOT gut related. very nice complete listing youve done i just wish i could be more helpful.
on the water note...
do you have a friend w/ well water that you could shower there a couple times a week? it could help maybe.
