Analysis Please

I especially don't understand why Na3 was better than Nc3. The bishop move I see blocks my other bishop so that makes sense why it's a mistake. At the time I just wanted to lock down the defense of that pawn. I found the tactic to win a piece through a check on the king, but didn't realize that I could've done it earlier, instead I played to trade for the queen, which he could have avoided.

Who or what said Na3 is better?

And by better, what do you mean?

Stockfish likes Na3 if you only give it a few seconds to think.  I guess the idea is to travel to c4.  But really, this is just another demonstration of how poor chess.com's free analysis is.  Give stockfish just a few more seconds and it prefers nc3, the natural human move.  

This also illustrates that you can't get too wrapped up in every little computer knit and twiddle.  You should mostly be looking at things the engine calls blunders, and to a lesser degree, things it calls mistakes, and pretty much just ignore inaccuracies.  Computers are great for pointing out things like 14. bxh6!, a fun sac you missed.  But there are some things a human can help with that an engine never will.

Hence why I posted the game here lol.

Right.  Well I answered your specific question.  I'm not the type to annotate every move if you are even looking for that.  

If you are looking for other learning opportunities, rethink 15. exd6.  Its a common beginner mistake to think that pawn tension needs to be resolved by you.  It doesn't.  Black won't take the pawn because that just messes up his pawns further for no reason.  After exd6, bxd6, you either fix his pawns with bxb, or the black bishops really come alive and point towards you king.  Unexchanged, the pawn is a beachhead, cramping black.  Exchanging it just frees up black.

I wouldn't ever even consider. 7.Bd3. After something like 7.0-0 do you really think he's taking that pawn?

I agree that 15.exd6 doesn't look correct.

Nothing wrong with 9.Nc3 though.

I prefer Na3. From c3 the N isn't going very far. Black has potential weaknesses on the white squares of the Q-side and it makes sense to try to use the N. In the medium-short term, Na3 prevents c5-c4 and so prevents black's attempts to win the e-pawn after playing Be7, but white's N is probably heading to e3 and maybe f5.

Didn't mean it personally, js I posted it here because the computer analysis didn't make a lot of sense to me.
