Yes, Yes, No (I very rarely flash dirty, too ocd). I actually never tried to boot with the included kernel, I really like AK (704 pirate) right now so I flashed that before my first boot. I don't mind sharing at all, just don't want to step on anybodies toes. Currently the build I am using is modified and stripped of anything I don't use/like.
Getting it setup wasn't too bad, I do know things were a little different than the pa guide for me. I'm using Elementary OS beta 1 (awesome distro for you linux guys/gals). Took some research and like always, patience, but it's definitely worth it in the end
