Grab a bunch of ammo and magazines and shoot the snot out of it. The range result(s) will dictate wants and needs to your personal preferences.

Don't over lubricate, this is NOT a centerfire AR15. 22lr ammo is dirty and over oiling will gum things up after a while. I lube mine with 4 drops, one on each rail of the bolt and 2 on the recoil spring assembly.

Most of all, enjoy the new rifle! They are fun
