Need some carification on my ingredient choices and hop boil timing

This question isn't easy to answer - at best it's subjective as to whether it will be the result you want or not. I don't know the final gravity or IBUs that this recipe will produce - I could find out, but then so can you with the free tools available - simply put your batch size and the ingredients into a recipe calculator like brewtoad to determine the likely OG and IBUs. You want to aim for a 1:1 ratio between OG and IBU.

When bring from extract, strong beers can have a high finishing gravity due to the non-fermentables in the extract. I'd suggest substituting a few pounds of LME with sugar to lower the resulting body. Also keep in mind that brewing a high gravity beer is more involved than simply adding more ingredients - temperature control and yeast handling become even more important than for regular gravity beers, so it'll be a good start for you to read up on those if you're not already familiar.
