I use Stuffit's 'Destinations' bar and extract to the relevant folder (I had to turn on some options like dont use a containing folder etc)  ... this sorts it out :) I went almost 3 years manually placing things and I could have done that the whole time :P

Also I hear BetterZip does it well also ... but havent tried it (BetterZip being half the price, and offers a free trial so you could test it out and see if it is what you want :))

Stuffit Deluxe Link (not sure if the other versions behave the same):
