Coming up on 100,000 miles

Hi everybody, I am a long time reader on these forums and have browsed many of the threads and have learned a great deal in the process. My 2004 Prius is coming up on 100,000 miles very soon, and I purchased the car used with about 79,000 miles on it, about six months ago, I drive a lot! Could some one please tell me what services I need at a minimum at the 100,000 mile mar, based on your collective experience with these vehicles. I have already read Galaxee's thread about such issues, but maybe somebody could summarize everything for me! Could you also tell the what the average cost for all these services would be, and any more tips or tricks to tell the dealership you might have.

Thanks,

Justin H
