Butt butter is a lubricant to limit chafing and diaper rash when your bottom gets wet with sweat after being on the bike for long periods of time. I don't use it, and I am a fairly avid cyclist. I occassionally use Monkey Butt, a powder to keep you dry. If you get a good pair of bike shorts, and get off the bike every 45 min or so, you wont need any of that stuff. Most people don't race on the Katy, so I would imagine that you will be getting on and off your bike a lot, and won't need any of that stuff.
This thread is becoming a somewhat exhaustive blog on all the things people do to get comfortable on a bike. And it is way too much information for most novice people who just want to go out and put a few miles on a bike over the course of several days. If you want to run all this stuff down, have at it: If you want to learn all the tricks, have at it: etc. Otherwise, most of the things people are discussing are for people who ride a bunch. My recomendation is to not worry about a lot of it, and have fun on the trail---Not getting bogged down in the minor details that won't matter, and in fact will get in the way of having a great time on the best RailTrail in the country.
