The HHOF is right on the subway line, which to be honest, isn't the best public transit system for city access, but it can get you quickly to the ROM, Queen's Park, etc. You may want to check to see if Toronto FC are playing while you're in town too. Card shops - I don't think right down town (rent is too costly) but if you're coming the August 21-24 weekend, that is FanExpo weekend... it'll be crazy down there and if you have any interest in that type of thing, super fun to go at least once.
