A lot of people are going to tell you to save for a 1*2 but at the end of the day it is your car and it's up to you! I have a 1.2 16v clio also.
You can get your paint code on your drivers door I believe.
My suggestions, go for 172 or 182 alloys, either will look good.
Air filter sounds fine, when you say cool overs, I assume it was autocorrect and meant to be coilovers. Hmm coilovers are quite dear tbh, to minimise spend I would go for some lowering springs. Don't go for window tints, get a 172 kit because if you get the 182 kit, you'll have to get the twin exhausts at the rear.
