Maybe a set of saddle bags, lets you grab a few groceries on the way home and store all kinds of stuff.  I have a set from vikingbags, think i paid about 150.

I shouldn't attempt to dampen your enthusiasm, however, matte black makes you a lot less visible to motorists on cell phones, and motorists, truck drivers etc in general. Matte black blends very well with blacktop. I would wonder why you would want to be on the phone while riding, with respect, riding demands pretty much full on concentration, and for what you spend on a phone mount, you might get a much more useful Raptor petcock, Savage petcocks can be unreliable. Talk to the techies here about, I'm not one of them, about various exhaust and carburettor  jet changes you can make at low cost. How old are the tyres on your bike?

Some type of storage is almost required if you are going anywhere out of your ''around town'' area, bags are the norm.
You WILL get caught in the rain once and a while. Keeping things dry is better than letting stuff get wet.
GET A M/C RAINSUIT.
Now take some advice from a lifelong rider. ( and I am OLD!)
The 3 rules of m/c rainsuits ---
Rule #1- Get a GOOD one. (A $2.99 poncho from Walmart is worse than useless at 50 MPH!)
Rule #2- ALWAYS have it with you. (Riding home from a chili cook-off at a park can be just as cold and wet as riding home from Yeehaw Junction when it storms.) (Yes that is a real place.)
Rule #3- Most importantly, Put the rainsuit on BEFORE you get wet.

It came with a set of easily removable saddle bags, I took them off for the remainder of the school year as I park in a parking structure and the less it can get messed with the better. The phone mount would be used for navigation and navigation only. I will look into the rain gear! As for the paint, there are just scratches here and there and by the gas cover the pain is like chipping and turned the white paint yellow. How hard is it to install the petcock?

Ride it. Spend your time and money just passing school, riding, learning to maintain it, gathering tools , and once you have ten thousand or so miles on it, if you just aren't satisfied with it, you'll be ready to decide if it's the bike you want. If you've Customized it to suit You, your potential customers are limited.
Take the safely course.
Keep maintenance records.

I use this one for my ride. It seems to hold my phone in place pretty well.

Once upon a time I scoured the internet to seek out all the awesome mods I could start doing to my bike. (84 Ascot)

I think, until you've got a whole lot more miles behind you, that you should just ride the thing and fix problems and/or do performance-related mods as you discover things you want to change.

Doing a bunch of stuff you've seen on the internet will probably either overwhelm you, or you'll end up with a silly bike that's too messed up to resell for much money and kinda sucks to ride.

Just breathe, ride and enjoy young one. Maybe pick one or two things you'd like to improve about your bike at a time that won't mess it up...

Protip: Removing the belt guard is a noob mod and does nothing but mess up the bike. Don't do it. Yes, some guys do it when they build some sick cafe build, but think about how they're using their bikes. They take them to rallies/shows/joyrides and probably have another bike that they actually ride for utility. This is your one bike and thus you should keep it as rideable as possible.

Protip: Plastidip is cheap for a reason. Good for small things that won't see any abuse, but will not last on a fender or gas tank...
