Paintwork, mods etc on an old bike ('86 FZR 400)

[tzr]

Been mentioned before, binned the bike on it's LHS.
Main cosmetic damage was to the bottom L/H fairing, I've just ordered another in blue primer.

So, some advice and opinions please!
Shall I bother doing the one panel or respray the whole bike?

I have an airbrush and compressor, what types of paint will I need to do this properly and how would I go about colour matching? I know it's a cobalt blue, just not the concentration.

Can get decals done for free due to father

Lastly, any ideas as to what would spruce it up a bit?
Was thinking of getting a smoked screen, found one for £46 posted.
Oh and the mirrors came like that when I bought it

Got a Carbon Can Co titanium end-can on ebay cheap; (£80, someone bought the wrong can for their bike)
Not received yet but here's my photoshopped version

I think it'll look much better!
