I forget where I got it, but last time I was accepted in 2012 there was a program guide for parents in a pdf file online. I don't have a link for it, I just printed it out then, so it may be something that everyone gets eventually when they are accepted. I've been accepted for 2014, but I haven't seen anything like that yet. There is also a for parents or family section of the official DCP website.
The working conditions are pretty much what it says on the official website. I'm not sure how they deal with roommate issues, I would imagine that it would be difficult to switch roommates and they would encourage you to work out your issues before getting to that point. I don't quite know what you mean by tax or college issues, I imagine these are specific issues that may be difficult to find information about online that is helpful.
In general, college issues would need to be handled by your daughter's college rather than Disney. Disney doesn't dictate whether or not you get credit, or need to take classes, or financial aid, or anything like that. So most likely any kind of college issue you would probably want to speak with someone from the college.
Also, I don't mean to come off as rude, so please don't take this the wrong way, but it may be better for your daughter to worry about some of these things, like roommate issues for instance, rather than you. Obviously as a parent you should be concerned about your child's well-being, but many students use the program to kind of spread their wings and learn to be on their own, so you may want to see how much your daughter wants you to be involved with some of these topics.
