I'd buy Xenoforms and a few others that were more "fluffy." Are you planning on using the Alternity mechanics, though? If not, "crunch" books won't be of much use to you.
Personally, I'd do Dark*Matter as d20 Modern with d20 Call of Cthulhu Sanity tacked on. You could potentially even use Cthulhu psionics and spells, if you think the flavor is right (I do) or steal Ken Hood's psionics system if not.
