Adding to what Sara Anne wrote much of the dietary suggestions are mostly that. Suggestions. While they can't hurt as they are great for some minerals they have not been proven for much...maybe in the exception there has been a lot written as anti-oxidants but, I not sure that even has been proven. General health, walking + exercise keeps the body running just like a car. If you don't use it for a month it runs down. Eating in moderation and nothing to excess etc might be the best item I have ever been told.

Welcome to the Forum, Larry! While you may not quite realize it yet your diagnosis is about as good as it gets, other than "no cancer." Congratulations!!
What is important to remember is that this type of cancer often returns. I presume that your urologist has you on three-month recalls for now. it is IMPORTANT that you keep these appointments religiously. Any recurrence can be found and dealt with immediately.
As for the rest, opinions vary. Remember that whatever caused the bladder lining to become "unstable (ie susceptible to becoming malignant)" probably happened many years ago and other than smoking and a few more exotic reasons no one knows exactly what these causes might be. No matter what happens in the future good health will be on your side. Please be careful of "Dr. Internet" and "word of mouth" recommendations. Unless they have SCIENCE behind them, they are probably worthless. Hydration is probably a good idea.
I have never seen any evidence that cranberry pills do anything for any condition. There is some evidence that pure cranberry juice (not cranberry cocktail which is mostly apple juice) may help in some cases of UTIs (If you have ever tasted pure cranberry juice ...or the similarly touted pure pomegranate juice you will understand why it would scare anything away!!)
I have also never seen any evidence that Bladder 2.2 or Oncovite have any special effect. (My urologist said that it "couldn't hurt" so I do use one of these as my multiple vitamin.)
Here is the latest from the National Institutes of Health:
