Sorry been having a little time off.
A couple of pointers for laying out your UV`s
Make sure that you ensure that your UV`s are evenly scaled, best way to do this is to use the chequer map and ensure that all the squares are the same size.
When laying the UV`s out give yourself an easier time by placing them in a sensible order and keep them as grouped as possible using all the available space.
Always make your textures around twice the size you actually plan them to be,it is a damned sight easier to shrink them down to size than to increase them later.
Stitch as much together as you can, this will help you reduce the amount of seams you may get and makes it easier to line up painted details.
Feel free to post your efforts up and I will take a look and give pointers where I can. Have a look at baking Ambient Occlusion maps as these can really make your models pop.
