Hmmmmz where to start...
The first mod should be Frame Sliders, Then SS Brakelines which nobody even said anything about or I missed it. Then comes a DB windscreen IF you like them and to help with the wind protection especially if you plan any long distance riding or high speed runs.
Unless you plan on trackdays which I might of missed that also you can save ALOT of money by not buying alot of the things posted...LOL
I would just setup and play with the stock suspension until you get better and do alot of trackdays THEN I would buy a new suspenion, but until then save your money.
Performance? Depends on how much power you really want? I personally just do the slipons,filter,velocity stacks and PCIII WITH dyno tune, not a canned program. I hate people who spend the money but skimp on the tuning..
Tires? Burn the stock ones and then try out some different ones until you find the kind ya like best. I personally hate Dunlop and like Metzler, Pirelli or even Bridgestone.
Rearsets? Why? unless you are doing trackdays you don't need them.
Quickshifter? Why? unless you are doing 1/4 mile passes you don't need it.
I think that's all for now
