I had an 08 12RT and did 47000 miles. Never bothered with fuel pump awning nor alternative screen but found the stock seat to be very poor for the pillion so fitted Kahedo seats which I bought second hand, still expensive but worth every penny! The BMW comfort seat is also very good, and arguably should have been fitted by BMW as standard. The infil panels are OK, I fitted some but then removed them as I didn't like the look of them. I've still got them if anyone wants them. A fender extender is def worth it as well.
