Pan mentioned it before, but do make sure you are setting ALL the surfaces to White otherwise the surface color will mix with the map color, and may be why your irises were getting muddied-up. Also, if you want to go crazy with the mix-&-match mapping, you can use UVMapper (link at right ->)to easily create new material zones on any part, or any sub-part of a part, that you might want. Like, if you wanted to texture the skin from one map but try different maps on just the face. ....Hey, (slaps forehead) that's not a bad idea!
