Hey Nathan,
A multitude of symptoms may be present w/ bad/outdated programming. Worst case are the random misfires, driveability issues. A quick way to see if your car has been updated w/ the latest is to look for a fairly large sticker (either on the radiator support or strut tower) under hood. It will give a date and pcm software upgrade #. As to your 2nd question we don't have access to shops that could perform this for you ( as the moderators are located all over the country) but I do know that 2carproJack is in California and may be able to help ya, just pm him. I would also recommend you hit the phone book and call around to some of the larger shops in your area and ask if they can re-flash your pcm.
You can also post some of the symptoms your are experiencing here and we may be able to help you further. Let us know!
Chris
