Well I would say that unless the cat and hamster grew up together since birth with constant contact and no food availability stress, then the cat would see the hamster as a potentially delicious meal, just the same as a mouse. Any thing bigger, say an adult rat, and the cat would weigh up its options as the rat has potentially damaging teeth and is bigger and would fight.
A hamster wheel is used in the cage and is powered by the hamster its self. A hamster ball is what you put the hamster in to exercise when you are cleaning the cage. A hamster ball is heavier so would probably go a bit slower but both are actually powered by the hamster its self so it depends on how fast it goes.

I have seasonal allergies and a hamster. I used to keep my hamster in the basement and now she is in my room, but there isn't really much of a difference. so no i don't think that a hamster would make things worse, but if you are still unsure don't keep the hamster in your room
A golden hamster would probably like a cage that is normal size and a few tubes to crawl in. They also love hideouts at the top where they can rest
