Lowering the front will reduce ground clearance, no good.
Raise the rear +1
Set-up the suspension for your weight
55 profile rear tire
+1

To clarify-
Raising rear changes angle of front forks, thus making it feel lighter and more agile on turn-in. Trust me, it's a very noticeable difference, and cheap at $50 +/- for rear raising dogbones that replace the stock ones. This also improves ground clearance.
Rear tire- 190/55 instead of 190/50 has a profile that is less rounded and more of a peak, puts more rubber on the ground when leaned over in turns. Also raises the rear of the bike 0.3 inches.
These things EAT tires, just wait until your next one wears out and replace them as a set. Dunlop Qualifiers are not expensive, but are very sticky and predictable- HUGE improvement over stock tires.
43 tooth rear sprocket- using the same chain, takes up more of the chain thus pulling the sprocket closer to the front of the bike, shortening wheelbase which increases nimbleness.
Read books. "A Twist of the Wrist" by Keith Code is pretty much the Bible of cornering science, I read it before I bought my Busa and has helped tremendously from chickenstrips to scraped fairings and no chickenstrips.
There is NO substitute for mileage- get out and ride it!! Ever play golf? Heard of swing cues? Think about what you need to work on in corners and repeat them to yourself as you approach and go through corners. Think in advance of what you will do if you get into a corner too hot and have to react- this will avoid panic mistakes. Most of the cornering wipeouts that occur, the bike could have made it through the corner, but the rider couldn't.
