Coming to the party a bit late, but wanted to offer my thoughts. You stated you would like to run 12.0 or quicker for sportsman? To guarantee 12.0 on a hot day build your car for 11.7x on a great day! Because when the heat of summer hits, you will still need to run 12.0.
IMHO you need more cam, more stall to match, (4500?) deeper gears and less weight. That is a lot, I know, but you are asking for a good performance boost. E85 and more compression might be the easiest power boost, but doubt those two changes alone would get you what you want. There are several routes to your desired power/et level, and a lot of research will help you get the most out of your budget.
