First of all, I havn't heard one good thing about Jim's Auto. Don't even bother looking there. Metro does have the upper trim and will have the second batch of lower valence trim out in the spring. The valence plastic piece is avaiable used. I've seen them on E-bay multiple times.
The clips that hold the grill trim onto the front end are NOT reproduced. You will have to find used ones. Post a wanted add on this site(and others), you would be surprised what is still out there.
The grill trim is anodized aluminium...not stainless by the way. There are companies that can re-anodize those parts but it is very expensive.(as much as buying a new replacement)
