I'm a regular extract brewer which is pretty rare on this forum, I think. Been brewing that way for years. Here are my thoughts, feel free to ignore them.
I stay away from dark LME or DME. If I want to add more color or a particular flavor I prefer to use steeping grains. In my experience, dark DME will add to the color of the beer, but not necessarily flavor. Steeping grain offers more control. I stick to Pale, Golden, Munich, or Pilsner extracts.
If you are doing a partial boil, then I would recommend adding half of the extract at the 15 min mark, rather than all in at 60. This will allow better utilization of the hops, and reduce the milliard reactions (which darken and add flavors). On the other hand, you might be going for these results.
When mixing different varieties of hops, I try to mix hops that work well together-usually from the same or similar families. Not familiar with Aurora, or if you considered this. NB and Willamette should be a good mix.
With 82 IBUs and 1076 original gravity, you are probably making an double IPA. It will be on the dark side of the style. With a big beer like this it would be good to pitch 14g of yeast. Not sure how much is in your packet. Try to keep the temp as steady as possible.
The great thing about homebrewing is the freedom to experiment and make what you want to make. You will probably turn out something good...but very different from the #9.
What kind of beer would you like to make?
I would highly reccomend reading How to Brew, by John Palmer. Wish I had read it first. Its better to buy it, but to get started, an older edition is online at:
