#1 - There's no way I can go with John being 28 in S1, IMO he's done too much with his life to be that young! That means I'm going with the 35-36 in S1 which is much more believable.
#2 - I've always thought of Harry as older. I don't think there's as much of a gap as there is supposed to be between Mycroft and Sherlock (7 years I think) but around 3 or 4 years feels right to me. Part of it is the vibe I get that the tables are kind of turned with them, that John has had to look after his older sibling, rather than the other way around as it was when they were little kids. I have no evidence for this whatsoever of course.
