Skinning a model with Unwrap UVW

[hitmanbob]

So im starting to embark on modeling (finally) and i cant seem to get the UVW unrap to work right(or maybe i hav no skill, your choice). Anyway, im trying to skin the master chief model, i used the gbxmodel importer thing and got that all firgured out, but when i do a material editor and choose the dds file and apply it to the sellection, the MC either turns white or it get strtched really weirdly(like lines going down him). When i try to do the uvw unrap i cant seem toget it to give me a better view of the mc.

Any help

BTW:From the GBX model i deleted most of the secodnary frame(except visor) and all te markers then attached visor to the almost full guy, here is a pic of what i have done so far....
