Why are you mixing DME and LME of the same malt? Why not use just one or the other for your extracts? If you have access, I would recommend just using all DME, as you get a better bang for your buck since there's some water in LME. Also, that's a lot of caramel malt, which will result in a very sweet beer. If you really want to showcase the hop with low alcohol, go for 6 lbs pilsen DME, and at most 0.5 lbs of a caramel malt. Definitely try to keep it simple, so don't add a lot of specialty grains. You could try adding some corn sugar when you start the boil (about 0.5 lbs) to help keep the beer drier. Your hops look pretty good, but I would do something like this: 1 oz at 20, 1 oz at 15, 1 oz at 10, 2 oz at flameout. I would also dry hop with 2 oz for 7-10 days and then add 3 more for another 10-12 if you really want a lot of aroma.
