I'm sure you know to just take it easy, changing only one thing at a time and start with the bike in the best state of tune you can.
Yes it is a pain, yes it takes some time and yes you will probably have to buy several jets.
However the good news is once you know what your bike likes you will probably only change jetting twice a year!
Well, that is unless you like to fiddle with the bike, (Guilty my own self)
