Upgrade your legs to a standard road double.

Wheels and tyres will get you the most bang for bucks

I have the same bike, albeit a triple.

What kind of riding do you do? Unless we know this an upgrade question is very hard to answer.

I suspect wheels and tyres would be the only things you would notice!

Perhaps lights for the forthcoming winter for some night training.

No need to spend £500.

Caad 9 is a great frame, I have a mate racing on the continent with one of those tooled out with Durace or SRAM Red. Another mate races and Ultegra equipped one. Re upgrade, it depends what you do with your bike and how strong you are. If racing is your thing, sort out a gear set that includes a standard racing chain set.. Try some really good fast tyres, the cheapest 'upgrade' for most bikes.
