Grades don't matter until they identify you as a prospect they're interested in. Or unless you're going to be a senior and are targeting Ivy/Patriots/HA D3s. Plus freshman year grades don't mean much so I'd trim that part out.
Just - Hey coach I'm Jimmy John, a freshman pitcher from Central High in Nevada. I have always been curious about ____ University and am interested in your program. I'm a 6'4 190 lb RHP.

Don't expect a ton of responses. The responses you do get will most likely be camp invites, just generic. He's in very early so just get the feet wet for now, maybe somebody comes to take a look, maybe not. Good to start early.
