They shouldn't be tight, but not slack either, they should just about slip in, so when your o-rings are old and swollen, they don't sit in the bore correctly, if they are a dense o-ring, they will pinch the shock shaft and impede movement, if they are soft o-rings, they won't seay correctly and leak.
As for shock building, my Schumacher and Tamiya shocks only ever get built finger tight, as Jimmy says, and they only leak when something is worn. If you have cranked on them like a Gorilla on Speed, damage is already done to the seals and the moulded plastic threads.
