I doubt anyone wants to comment on your belt change, but if you are in 2 years on the new one, leave it one year for the change in theory, you are nowhere near the official mileage or the advised mileage for a belt change. However in 2 years of course it has covered same distance as previous 5. As well consider where the cambelt was changed, you want the Alfa specialist method for the cambelt change.
Get your 10mm spanner out and have a peak at the belt yourself.
Get a spare pin for the clutch pedal to master cylinder rod connection while you at it. Handy to keep in the tray if any chance the pin busts.
Check the oil and get to know its consumption over the months. I would always change your oil filter for the price at oil change time too.
Make sure the timing is checked, all trivial info I guess.
Autolusso I can recommend, I have only ever used them for the major stuff. Only now out here have I appreciated their thoroughness, we do not have such comprehensive knowledge here as those guys, sadly, but she still ticks along reliably.
