Arranging UV unwraps and referencing

Firstly I would like to thank Agida Iwo-Sse for the use of this texture http://swg-piloten.com/html/x-wing_texture.html. I did not use all of it, just some of the engine decor .
Also http://www.google.co.uk/imgres?q=tie+fighter+side&um=1&hl=en&biw=756&bih=526&tbm=isch&tbnid=euUPlGo_dVNrHM:&imgrefurl=http://www.erikstormtrooper.com/vehiclestickers.htm&docid=GWhM9-vovcQCsM&imgurl=http://www.erikstormtrooper.com/tiestix.jpg&w=1018&h=635&ei=F1bRTtGvPIi5hAebuamgBw&zoom=1&iact=hc&vpx=429&vpy=216&dur=202&hovh=177&hovw=284&tx=224&ty=141&sig=116454246868238874563&page=6&tbnh=129&tbnw=207&start=33&ndsp=7&ved=1t:429,r:6,s:33

which I found useful for the Tie fighter wings.

The texturing of the xwing was very straight forward, however the tie fighter has a large poly count, so I am finding it more and more essential to move the polys around in the UV template to get a better, more accurate detail placement.
