Lp
I'd say, take it slow. Don't mess with anything unless you have played it a while and are sure something is not correct.
First, I always put new strings on my new guitars. This always improves the sound immensely and often "eliminates" buzz that you heard with the factory strings.
I wouldn't do any set up since you haven't done one yet it sounds like. Why experiment with a beautiful new ebony LP? You can really mess things up and then it will cost a lot more to get a pro tech to get it right. Plus you could crack something, severely gash the ebony surface with the screwdriver, etc.
My music instructor was a tech for over twenty years and he does my set up work free at my lessons. He knows what he is doing and even does a strat in a few minutes.
Strings. Put new ones on right away and see how much difference that makes in perceptible sound and feel.
I have had several guitars come set up almost perfect from the supplier, like MF.
Which model standard did you get? Plain top, arch top, or arch top with flame maple? That one is called the plus top. I have a regular arch top type one and a plus top. Both are really nice guitars. Black looks really cool in a LP.
Listen for buzz on the clean channel of your amp, not the drive channel, because some drive channels impart a buzz tone to the sound as part of the overdrive/distortion.
Your teacher, if you have one, will probably set it up free. But you might just get lucky and have a satisfactory guitar that you can just start playing and enjoying.
What amp are you going to use with it?
Congratulations and have lots of fun, which I'm sure you will.
