Well good to hear. I'll note the bulbs unless they are really really cheap generic no-name will have very small script etched in the metal rings somewhere identifying the manufacture, type, etc. The post by uberwgn yesterday shows a good example of it.

As for the SilverStars, you need as mentioned the Euro ones, not the blue american substandard ones. You likely have to order them via the internet.
Or perhaps you can find some Philips Vision Plus, again not the Philips BLUE

As for the outside assembly clips, about $2 each from your dealer.
2108260084 outside large lens side clip
and
2108260184 inside clip

As for the wiring, I couldn't determine that, it looks like there is a cable say from a connector in the engine bay to the assembly, that cable is $30 or so. But nothing in the parts diagram for wiring inside the assembly.

PS the dealer sells bulbs too, 400809000007 Might check pricing.
or 66809999 which is the spare bulbs box, and might be a better deal.
(usually that contains a H7,H3, some tail lamp & licence plate bulbs).
