Hi matey

Welcome to forum. I'm sure more seasoned regulars will be posting shortly, but here's my (relatively novice) opinion...

It sounds as though you might have to get your truss rod adjusted to stop the fret buzz at the nut end - there should be a slight concave bend in the neck - look down the guitar neck from the bridge to gauge whether this small upward bend is present or not.

Secondly, after getting the truss rod action adjusted, you may need to adjust the height of the bridge to lower the action at bridge towards the fretboard...

Which may lead to a need to re-adjust the truss rod.

And then the intonation...

I've set up my own electric guitar by myself, but you may seriously want to get it set up by a pro. Most guitar shops will offer the service, either in-house or through their preferred set-up dude. Cost is not too much and is definitely worth the outlay in getting a guitar that plays well and doesn't frustrate you - and frustration may end in you giving up learning!
