Not much cash I hope ;)
DO NOT bother with light QR especially cheap and light. If you want light get Tune if not just bare 50g more weight and get something solid/shimano. Ask dammit about BB30 and light QR combo he has a good story.
I bent a light and cheap (PZ racing) QR in one ride. The rear wheel came out. I dont even produce enough watts.
Oh and good call on 7900 brakes; I am sure you will like them. I went 9010 on my other bike.
There's a stunning 50cm caad with 6800 and Cannondale spider cranks on eBay currently, I expect that will go for much cash!
