Transport question

[tsaress]

I'm trying to plan my transport in advance so I know how much to save for it.
I was wanting to know the sort of costs I know they change but just a rough idea would be good.

How much is it from Frankfurt airport by bus/coach to frankfurt center?
How much is it from Frankfurt airport by train to frankfurt center?
How much is it from Frankfurt train station by train to fulda center?
How would I get to the holiday inn from the train station and how much would it cost?

Thanks in advance.
