It is really a pretty easy job. Take your time, do your research ( what jets will suit your needs best). Doing it yourself will not only save you 180 bucks, but i have yet to hear of anyone who did redo or tweak the bike afterwards each bike, local, and dealer will be different. If i spent $180 each time i tweaked i 'd be broke.
either way if you do it or the dealer (Pete's?) have them use the stainless allen screw kit from bellacorse or newbonneville. It is like $6 and the best $6 you'll spend. Also make sure they remove the air/fuel caps on the carbs. These will need to be tweaked with the weather.
I live across bmore (same altitude)and here was my best set up before the freak.
130 mains
stock pilots
tbird needle (14 dollars and worth it although i read better things about the thruxton needle)
near three turns but that changes with the ambient temp
If you go to Petes let me know what you think of their service. I have heard good, but what have they done for us lately.
