What Happened to Andys wife? What relation is Ant Bee to andy? Is she Opies Aunt or Andys Aunt Or neither? How Could I meet Andy Himself and get an autograph?

Viewers were never told what happened to Andy's wife, just that she died. Her name was never given either.
Aunt Bee is Andy's father's sister so she is Andy's aunt and Opie's great aunt.
Sorry, I can't help you out with your last question, but I think I read over at Miss Crump's Blackboard that he will be at the unveiling of an Andy and Opie statue somewhere, maybe in Mt. Airy, NC. I guess you could attend that and at least get a look at him. If you would like to go to Miss Crump's and try to find the post, I'll post the link. IMO, it's the best TAGS message board of all.
