I've flown ORK-AMS and DUB-AMS at least 30 times in the last year, so I'm very familiar with the aircraft type...
The first and last (29th) rows are best avoided. Otherwise, I'd just recommend as close to the front as possible for a quick exit.
The second row of over-wing emergency exits (14?) has the advantage that you can recline your seat and the person in front can't, but I normally avoid the emergency exits so that I an keep my laptop handy.
Unlike the 737-500s (which definitely got narrower towards the back of the aircraft), there doesn't seem too much difference between the seats in any given row. Considering that I'm 6' 4", I don't have too much problem on EI with seat pitch.
