Hey Quark, to be honest with you, suspension set-up will only get you so far. You don't weigh much (IIRC) and this means that the only way to get a good set-up is to fit correct rate (strength) fork springs & shock spring.
For example, your bikes front fork springs are rated at 9.00kg/mm. For street use, this would suit a rider of approx 100kilo's!!!! A 50 kilo rider would need a spring rate of about 0.700kg/mm.

Price is in USD but you can get Racetech springs from just about any decent bikeshop. Price should be about AUD$180 - I've bought them before.
Not sure about rear springs as Racetech don't list them yet but a call to a motorbike suspension specialist should get you pointed in the right direction.
In the end, a set of fork/shock springs (supplied & fitted) may end up costing you almost as much as a cheap steering damper, but you will appreciate the difference.
You will get heaps more confident in your riding which translates to becoming faster and safer.
