Spiderman and his many suits are the reasons I got into customizing. Most of them have decent factory editions but not armored or cosmic, custom only there. And one you may be missing or just not interested in is Ends of the Earth, oh and Negative Zone. Those would be custom only as well. Other than that the suits you want are pretty easily found by just searching those descriptions. Many came from the spiderman origins line (classic, iron, 2099, black) Then of course the raimi movie figs. And the lines out most recently in roml have big time (stealth), FF, miles, superior, n the new movie versions. Hope that helps some. Good luck!
Edit: and Spiderman Noir, amazing bag man. Both custom only.
