Just picked up a new Dark Gray Metallic 09 XT yesterday and one of the first things on my list is to get some good wax/sealant on this beauty to keep it looking great. I know there are already some other threads on this so I'm gonna go off of some of those and see what you guys recommend.
So when I got to work today I made sure to park in a nice open spot trying to avoid dings and such. Turns out the reason it was nice and open is everyone else knew about an effed up sprinkler that was just waiting and plotting to spray all over my beautiful new paint (sprinkler ->)

and now there's a bunch of water spots all over the sides of my car. I saw some recommendations to use a microfiber cloth and vinegar to get rid of them-this was for on the paint right? Should I dilute the vinegar at all? After I wipe them off should I do anything to remove the vinegar like wash/rinse it? If it wasn't clear before that I'm a complete noob to having a car I actively care for it should be now

but you know, it seems silly to get rid of water spots only to spray the car with water.
But I guess I'll have to wash the car anyways because then comes...
...some sort of wax/sealant deal to protect the paint and make it shine for a while. The two names I picked up on to do this were Klasse AIO and Turtle Wax ICE. Klasse seems to take the sealant route if I use it with Klasse High Gloss Sealant whereas Turtle Wax, well wax. What are the big differences and pros/cons? Is there some sort of combo of the waxing and sealing that people like to do?
Any other tips on ways to keep my paint job looking great? kthanx
