Cant say anything about the individual mods but here is what I personally would do, to ensure a clean setup:
Clean extract of the game into a new directory. Create a sub-directory for the downloaded mods in there and make sure you are running the latest modloader (2.0.7 if I am not mistaken), which should be in the same directory as the game itself.

The green directories are the game's default ones and have the original images that might have been messed up in your last load activity. 'Modded' and '.unpacked' are the default ones created by the modloader. Keeping things cleanly separated should do the trick hopefully. So move the downloaded mods into their own subdirectory and re-run the loading on that new install. Doing this will at least exclude any remnants of some old install.
P.S. Since this is html, you can easily check what the path of those missing icons are, by either looking at the source in your browser or simply by right-clicking and trying to save them - which should show you the path as well. I am almost certain that is the problem for them, either a wrong path or a wrong spelling.
