Life In 19x19

This was a game from this evening on KGS. I was maybe not feeling the sharpest, and so didn't read things through that well, but would appreciate some comments on where I need to put in more work. I feel my Tesuji skills are very poor, but my worst skills are in fighting..

I'm not sure but I think 15 was a joseki error on Black's part.

See this

Black is cut in two and one group is under heavy attack (or maybe even dead)?

No, your cut is too soon for W. See vars.

I now understand that the cut is too early, but black's hane is also too early right? Is variation 2 in your diagram better?
