When replacing the spark plugs should the rubber seals be replaced at the same time and any do's and dont's to be careful of ? Dealer says its easy to wreck the coil pack.. is that so ?

Replace the spark plugs, its easy to damage the coil leads, id change them all if it was my car, but beware of the cost as there are 2 coil leads per cylinder, the coils will not get damages then.
