The first piece is called the radio bezel. I think it is quite different depending on model year so be careful when ordering to be sure to get the right type.

The second piece is just a door handle trim. These are easier to find. I'd try ebay to start. Search for 'black passat door handle trim' or something similar.

Got it
There is a very dark grey interior color called Anthracite so you may want to check into that as well. The VW parts store at Jim Ellis VW seems to lump them all together so good luck!

Now that I think about it some more....I think the interior trim color should be listed on a sticker in near the spare tire along with the exterior paint code, etc. You may want to start there.
