My procedure was about the same, cleaned with soapy H2O, wet-sanded with 1500 grit, then spray to desired darkness (I did 4 coats I believe), and then for a matte finish like mine don't use clear, but for a shiny-er finish use 2-3 coats of clear.
*also, just debadge to your liking, I thought it looked a little plain without any badges since my car is a lighter color like yours, but do what YOU think looks good........here is a quick PS of mine w/o any badging......
