Regarding the front nuts. I also had to change them to use on Columbus forks and it was no problem to find nuts that worked...
Try losening the nuts a bit (so they aren't touching the dropout) and make sure they're not lose on the threads - I went through all the bolts at my LBS and couldn't find any that fitted. The ones that seemed to fit would be lose on the threads unlike normal nuts.
