There are several threads on this and if you search you will see lots of opinions. I have had some BB non-iron shirts in the past and I don't think they shrank much if any. You would not need to order a different sleeve length than normal.
As far as these shirts go, they were fine, but I ended up returning them because I did not like the feel of the non-iron fabric, so maybe I am not the best judge.
