Colour coded if not already done so, cup spoiler.
Tints... It's a toughy most of CS hate them, I for one am not fussed (I wouldn't get them myself) but hey ho each to their own. As for a carbon bonnet, save your money unless it's a track car get some 3M Carbon Vinyl Wrap and just wrap it matey. Looks just as ace. Oh Paint your badges, pick a colour scheme like I dont know my car is red, so I went for red and black, I have black badges and wheels. If it's blue maybe blue and paint your badges yellow?
Just make it your own like said
You can't go wrong on your own car in your own taste.
(and I have "lexus" lights but they are just black PH2 lights, so don't worry if you go for those.)
