You pretty much sorted I would say.
If you travel with luggage on the back the bolt upgrade is a good idea, check to see if it has a foam air filter installed, and if it's still in good shape (always grease the sealing edge of the filter to seal it properly) Definitely consider something for the seat (the seat pan is prone to braking as well). I run Tubliss with tyre shield which is great, or make sure you have the heavy duty tubes in. A USB charger and hella plug is also a good idea, there are two power points at the front of the bike which you could use (or tap into the power of the rally tower)
