you can use a normal mp if you need to add more detail,
before you ask,( dont take this explanation as an insult)
A normal map basically reflects light/poly in order to create a smoothing look, it used in every new game as far as i know to signficantly reduce poly counts, imgine it as wrapping you self in invisible clothes, not a very practicle example but there you go,

tadaa normal mapping program, its basically the Gimp, Generic image manipulation program and a plugin for the normal map filter
hmm what else could i cover...
Uv map? I think ill let someone else handel that,
But a brife description will help, uv maps are a model laid flat, its allows you to texture specific parts and then wrap them around a model again.
I never used animator so i cant realy help, ask Neodelito i think he uses it.
