ok well first off WELCOME!!! this is a wonderful place for tips and questions like this.
well as far as the passes they do have them but you do not have to pay for them. They are called fastpasses and they only have them on certain rides.All you have to do is go to a ride that has a fastpass machine insert your park hopper into the slot and it gives you a ticket that sort of looks like the park hopper. On this card there is a hour block of time. This is the time that you can go back to the ride and go into the fastpass line. This line is 10 mins tops you never have to wait long in it.
I just checked disneyland.com for you and... they DID have an offer like this but in it it says that the reservation needs to be made by april 4th so i don't know it they will do it. But you could call just to see. here is the link...
