Good advice here.
As far as your engine is concerned you bought a good one. there pobably won't be a lot of tuning needed out of the box.
New engines don't like to be at very high angles of attack,high degrees of roll, or be inverted. by the time you're ready for that so will your engine.
I hope you have an electric starter as it makes life so much simpler. Don't worry if you don't, but I'd make it one of my first priorites.
Good luck and welcome to the addiction
