I think each of you should pay for their own ticket, but that's just me - if you both don't mind and are happier this way, by all means pay for her ticket as well as yours.
As for telling Kate how you feel about her, what exactly do you mean? Just ask her about prom and if she says she really can't go, find another day that works for you and ask her on a date for that day. Tell her you'll probably ask someone else to prom but that you really like her and you are looking forward to the date with her.
