with you bonnet you have a few options, you can paint it, use vinyl sticker or you can get a carbon fibre bonnet and 2tonne it, with your badge you can glue it on directly to the grill with silicone adhesive but thats not a good idea, try useing silicone adhesive on the badge by glueing 2 tabs or aluminium wire to it, then pinning it to the grill.
