Hi annihilator, welcome to Holowan!
Before I can help, I could do with a few details, like what you used to model this: g/3dsmax, sketchup, maya... ? Around these parts, 3ds/gmax is the more normal choice, so some advice may not apply if you've used a different programme.
Secondly, have you had a look in the modelling and skinning tutorials section
Also, have you checked that the filename of the .tga matches the texture name-references in your model file?
