Am I doing it right?

Analysing my games that is. Well and playing them I suppose.

Hopefully I can post the PGN properly...

I think black passed a chance in move 16: .. Bb3 wins the quality. Or I'm wrong?

Yes, as far as I can see that is correct. Seems both of us were to focussed on the isolated pawn. Thanks for pointing that out.

EDIT: Actually a discovered attack with d5 wins back material so it's fine lol.

Okay, un-edit the edit. With the right order Back is up in material.

Damn tactics, so complicated.

Actually the endgame is probably my best phase, but like I mentioned on move 34, we both had 20 seconds left. Winning on time was far more important than a well thought out endgame. 

And If that was a joke I feel like an idiot now >.<

Just a word to the endgame: waiting for time control worked this time, but for future: move your king into the center and attack black's pawns.

Thanks to everyone who commented :) I definately learned a lot from this discussion.
