That's a great deal on a great bike! As far as cosmetic mods, I started with those first because I believed the bike had enough power. To me the first must have cosmetic mods are:
1. frame sliders (
t-rex is the best bang for the buck). I'm short and believe that dropping the bike is inevitable and didn't really like the looks of the engine guards that are now nearly impossible to find.
2. windscreen. I just wanted something that looked nice. I have the zero gravity sport touring and maier aero bubble.
3. grips. I replaced the stockers with pro grips gel grips and haven't looked back. They are more comfortable and look great.
4. levers. I got adjustable levers mostly to fit my smallish hands but also because of the different color. I chose the chinese ones that are on ebay. I don't think it matters which seller as I think by now they all come from about the same source.
At some point after you get a few more miles on your ass, you should consider upgrading the suspension. There are so many different ways to go about this, from the budget mods where under $100 and a little diy make vast improvements to the wallet busting traxxion full monty stuff. It may not seem like it now, but once you do that you'll find the bike even easier to ride because it'll feel more stable.
Since you already have an aftermarket muffler, you may want to make sure the bike is jetted if only for the improved rideablility (any performance gains are just gravy) like smoother throttle response that make it easier to control the bike. The bike is 10 years old so replacing the OEM rubber brake lines for stainless (like
fren tubo, another best bang for the buck mod) will not only enhance the bikes looks but improve braking feel.
5. not necessarily for looks but the

6. anything you can afford from devilsyam. I have the frame plugs and really want the sprocket cover.
The most important mod any rider can make has nothing to do with the bike. It essential to keep modding your mind by reading about and practicing riding technique or taking riding courses or doing track days then simply riding more often than you possible. If you find that you haven't been on the bike for more than a month or so, you should practice braking and low speed maneuvers more often.
I live in the Southeast so I don't have any recommendations for where to ride near you. Welcome to the forum and the FZ1.
