I don't care for victory malt and I don't find it necessary (certainly not in that volume), so I would keep it out. Also, instead of the pale chocolate, I would use 1-2 oz of Carafa Special II or even regular chocolate malt. From my perspective, the point of pale chocolate malt (which I love) is to get more chocolate-malt flavor with less chocolate malt color. Since you are making an American Amber Ale and not a Brown Ale, you want to reduce the roasty flavor to nil and just get color from the malt. Technically, you don't NEED any roasted malt if you are using the malt bill you propose because the 120L will put the beer into "Amber" territory, but it won't hurt to use a little. I would just go for Carafa Special II (or I or III) or regular Carafa I, II, or III, or some plain Chocolate Malt. As for the hop bill, I would go 60-30-10-0 maybe with Magnum-Columbus-Willamette-Cascade or Magnum-Columbus-Cascade-Cascade and Willamette.
