There is a book called "now that I have CF" by Solvay pharmaceuticals. You can only get it from a CF clinic. Most of the info I've come across has been on this site. Do some searches for "adult diagnosis" threads on this site, there are a lot of us with atypical CF.
I am 36 and have no lung damage yet, don't know of anyone else this old who cultures for a bug but doesn't have damage yet. There are several people my age who have similar health to mine with mild lung damage only, few or no hospitalizations and only doing a fraction of the usual treatments.
I did a post about high cholesterol once too this year, you can search for that though I'm not sure if there anyone else responded who has it.
