Here are my thoughts. The deadlifts and DB rows are awesome back exercises, but they are both very taxing and time consuming. Each set of those will take time to recover from and will sap your strength quite a bit.
You need to consider "training efficiency" in your plan. You've picked a lot of good exercises, but you need to whittle them down a bit to keep things to a reasonable amount of volume. If I had to choose, I'd probably pick the deadlifts, the DB (or barbell) rows, and the lat pull downs (or pull-ups if you have the means to do them). Remember, sometimes "more" is not "better". Pick a few good exercises and hit them *HARD*.
