For lenses, I'd look into:
14" Commercial Ektar---single coated. excellent color rendition, fast, large image circle, nice for up close portraits. A real work horse when it comes to 8x10 landscapes.
12" Dagor---superb for anything. Coating? What coating? It don't need no stinkin' coating. Never 'cheap' (unless its in an impossible shutter) but sometimes you can find them 'reasonable'
240mm G Claron---single coated, excellent color rendition, a large image circle if you stop down, interesting for portraits as it will pick up any imperfections of the skin but the focal length I find is flattering. It is very light weight if you'll be hiking ---but wait! You've got a Calumet metal monster---never mind!
19" APO Artar---big, heavy, simple beautiful! They'll yield negatives so sharp you can shave with 'em. Nice FL for portraits and "grand vista" type landscapes. Not cheap unless you find a barrel lens. Ones in shutters are rare and often quite costly---but IMHO worth it if not priced obscenely.
10"/250mm WF Ektar---another beauty. Single coated and needs a lens shade of some type. Takes series 9 fillters if you can find a slip-on adapter.Unlike the 240 G-Claron it is a big lens, but to my eyes yields smoother looking skin tones. Quite flattering. Lots of wiggle room at any aperture. Ansel Adams used one for more intimate landscaps so its got to be good! Probably runs the same if not more than a G-Claron.
450 Nikkor M---multicoated tessar ninja! Lots of sharp image circle---so much so that you'll swear its not a tessar
but it is! A modern lens. A very useful focal length on an 8x10. Not a cheap lens and never was, but if you dig the 'new car smell' get one soon since they've been discontinued.
Those are my recommendations, There are certainly other outstanding lenses from Ilex, Wollensak and Schneider too, but I don't know enough about them to comment.
Good luck!
