Hey, I've got a few pair of raw jeans too! I'll chime in and answer any questions you have, to the best of my knowledge!
As per laundry, fitting them for yourself can be quite a process. Cold/Warm water stretch and shrink the jean. Some people turn the jeans inside out and soak them to get all the excess indigo dye out and/or put them on, and sit in the tub and soak to get a better form-fit!
