Full exhaust, -1 +2, a really good tune for your bike, quick throttle and an air filter with some proof it works. This is not the fastest combination or the most you can do, but it is the cheapest best bang for money spent. The recommendations above are excellent, I wouldn't do more than head work, degree cams, and thinner head gasket.
Next lose weight either you, the bike, or a combo of the two. Then figure out how to get more aero dynamic. At high triple digits stream lining the air around you will make up for a lack of horsepower.
Learn to ride, practice getting to full throttle and always let off when you're ahead. :-)
