you'll definitely mellow out over time. Shoot, I had my FG sampling and when I drank it I thought to myself, this is what my beer is gonna taste like? Gross, but sure enough I bottled and now 2 1/2 weeks later it's tasting absolutely delicious. As far as your hop question goes, you can add a little less if you like. I'm doing a honey oat stout next that calls for 0.92 oz instead of the standard 1 oz. But what you have to remember is that really hop pellets are actually whole hops in a more manageable form and they are really about the same in IBU as comparing 1 oz of hop flowers and 1 oz of hop pellets. Its just that 1 oz of hop flowers will look like a lot more because they are lighter.
