Hi Ruth and welcome aboard.
Having owned one of these fine steeds for the past 6 years (first 2 a road bike and currently a race bike) all I can say is - GOOD CHOICE...

If you are going to push it hard I would recommend a steering damper, the front does get a little light under gas and can be a bit of handful. I have a Hyperpro damper on my race bike, but had a Matris on my roadie and they are both fine, any of the name brands will do a good job.
There was a recall on the front wheel on the 04 model and If you have this year model it should have already been done but no harm in checking, your dealer should be able to do that for you with your VIN No.
I had no issues with my road bike other than some warranty claims on cracked plastics, and I don't believe the 2 subsequent owners have either (they are both on here) and the only complaint with race bike is the gearbox could be a little tighter as I tend to get a couple of false neutrals of I'm not shifting hard enough, but thats mainly when its hot (I do have a quickshifter which is a little tricky to get right.)
Check the rear plastics around the passenger seat as they did tend to snap at the mounting points and quite a few on here had them replaced under warranty. Other than that, keep it regualrly serviced and it will be a great bike..
