Questions about repair and radio Renault Clio

Good evening to everyone, I’m a student and I got myself a Renault Clio with 120,000 km to teach before. After the apprenticeship and almost 25,000 km more I want to buy it now, because it becomes too expensive for me as a student and I don’t use it anymore. I was at the TÜV now, because I want to sell it and did not get it, because I have to make the brakes new ( front ) and need new dancing. Wanted to ask if you can tell me that my selection is the right one for spare parts. I want to here no advertising for iwel pages but only show what I wanted to buy now. My vehicle data for 2.1 and 2.2 is 3333 and ABC. I need new brake discs and pads. I wanted to buy these here.http://www.bramen.com/…/mintex::mdb1628.html and twice the herehttp://www.bramen.com/bramenscheibe/nk::203909.html My car is BJ 2006. Question about the things shown above would be alreadyma if e.g. with the brake discs everything is with me.. Screws or something or something. If I still have to buy these extra… Cars are not really my world… And because of the tires I still have to look.. Wanted to buy W+S. Utility 175/65 R82 – knows who a side where I can possibly catch cheap ones? Should one buy for the tires also new screws to attach? Don’t fool me just I really have zero idea of cars… How to notice I think… Last question would be because of my radio.. Have used the search function already only I can my radio n If I hold down the button 1 and 6 for about ten seconds and then let go the radio “COD X 136” tells me – does that help me?… I’m new here in the forum and hope you can help me… Hopefully nobody feels bothered by so little idea ..??
