Only had time for a quick post before - but there are a few priorities to check out - hopefully all sorted but worth checking:
1. Is it on MEZ3 tyres? If so don't let it stay that way for any longer than you have to - I tried to wear mine out (wrong plan) but changed both when the rear wore out. Virtually any other rubber changes the handling immensely.
2. Is the headlight a UK item? A good number of the later models turned up with European headlights. There's a sticky thread
HERE that explains how to check. If it's wrong your dealer should fix it.
3. Has it been de-restricted? If not, no big deal - you can do it yourself or get the dealer to sort it at the first service. De restriction is done by removing a bung in the airbox and snipping a wire on the ECU (and taping up the ends). See
HERE
Get these checked then, by all means do the other things you plan - my priorities would be sidestand and shock (that Ohlins seems a real bargain).
Re the sidestand, I've never heard anyone that's fitted the Gixer stand give any negative feedback but there has been some from a few that fitter the VTR stand - that doesn't necessarily mean the VTR stand is worse - they may just be more fussy.
That Ohlins seems a real bargain. If it's the Falco-specific Ohlins, there was a rumour that it wouldn't fit with the Mille swingarm - I think this put a number off buying. I even repeated this myth myself until I saw a picture of one with a Mille swinger on the AF1 forum. I checked with the owner and it was fine - myth exposed.
It DOES have one disadvantage over the Mille Ohlins - it is not height adjustable.
Another thing really worth considering is a Scottoiler - the earlier you fit one, the sooner you recoup your outlay in chains and sprockets that you haven't needed to buy.
Hope some of this is useful.
Anyway, owning a new Falco is an experience to be treasured - enjoy it. It's the only bike I ever bought new (though DavShill has had 2 brand new Falcos ..... but that's because the first was nicked).
