Hi migga,
Have a read through here for some ideas about jetting.

You have the option of staying with you existing needle and change the main out to say 120 and the idle to a 45. The adjustable fuel screw is worth the money too.
Nobody can give you an exact "use this jet with that setup" as every bike is slightly different. The whole point of changing exhausts etc is to get that bit extra punch and rideability by fine tuning your setup.
People have also had success with the standard needle up to 2005 ( more clip positions to adjust) as well as the power up needle. Try the jets with your needle first and see if you are happy with it.
I would pull the snorkel out when changing the jets, but leave the other rubber piece in especially if you ride through water some times.
Hope that helps and any questions just hop back on for a chat.
