I doubt you are drinking enough at a time to do any damage. I think using ro (reverse osmosis) or di (distilled water) is fairly standard among people with sub-par water.
It's ambitious to consider water on the first outing, but there's plenty of technique to master that will probably affect the quality of your beer more than the water quality at this point.
perhaps a line of single hop IPA's - there's so many new hops out there!!!
