'Bout to join the club, have a few questions

After searching a for a few months, I found my FJ and I'll pick her up in a day or two (and post some pics.) I have a few questions about minor modifications/ looking for product recommendations .

-I want to replace the mirrors with convex mirrors for the blind spots . I've seen a couple YouTubers install Suma mirrors. https://www.sumaperformance.com/products/fj-cruiser?srsltid=AfmBOorQlpLmukMA9PuZld6L92Wh5gKPLPrshS67CSVu5MNB8v7eWTDf&variant=40380283846835 Are they worth it? Or any other less expensive recs over those?

-I want to replace the radio and add a better backup cam, looking for product recommendations.

-There are a few tiny chips I want to touch up, should I go with the official Toyota paint, or are other brands' color matches ok?

Thanks for any advice and suggestions, I'm excited to personalize my new baby!
