Hi,
Jason Edwards did a great UV mapping tutorial here https://simplymaya.com/autodesk-maya-...ut/?tut_id=309
I texture all my stuff after i have modeled it, I do a lot of interior scenes so i like to keep my objects as reusable assets. My workflow is create model UV it then create texture maps normally a diffuse map a bump / displacement map then if needed a spec map, translucency map...
If you have 10 objects in your scene expect to have lots of texture maps.
BTW if you want to buy that tutorial please wait the January sale will start today 
All the best
David
