Small black desktop speakers, tall stainless steel coffee canister (thermos), the monitors and stands you mentioned, flat black desk mat, black plastic toolbox or utility box and depending on your budget and how far you want to go with it (custom ccfl lighting for your ceiling), desk or tabletop made from a large slab of rock (unpolished granite?)
But, if I were you I would frame or hang up some of the pictures you posted in HD as inspiration and go from there. Once your monitors are set up just make everything else look sleek, minimalistic, and modern with a black or dark metal theme.
Good luck...
