1.  either append object or append object and armature should work.  to export them to another ap i recomend .obj.  its used by virtualy every app.

2.  uv maping  i have a mini tutorial up on it here.  go to the blender wiki to find more

3.  apply the object as a parent to the armature (or the other way around?)  or, apply an armature modifier to the mesh.  doing facial expressions gets alot more complicating and confusing.  once again go to the blender wiki to find more.  

4. the way to do this is physics simulations with rigid bodies.  it finicky and doesnt always work properly and takes along time to work, so your better off just handling your frustration.  not only that, but it takes a long time to bake, its sort of like  baking fluids but harder.

5.  a nobe is either somebody is spelling noob odly , or a node. in the case of a node, i can help.  Nodes are these completely awesome creations which help you link up certain properties of color and power to other.  they are used in material creation and compositing.  in the case of material creation they actualy save alot of time.  Creating UV maps and textures is not always the best solution, sometimes its nice to have a material that works on all models regardless of textures. to do this you can use a combination of material nodes and procedural textures.  nodes are realy usefull for creating more complicated materials like skin and oil  and assorted organic whatnot.  i actualy have the beginings of a skin tutorial on this forum that explains the extreem basics of the node system, and some more complicated things.  Compositing nodes however are a bit more complicated.  they can generaly be used to change the mood of a scene or combine different layers in different ways after the render and proceduraly throught the animation.  

6. the uv section in editing is a way of defining the how the mesh unwraps in UV mode. when you click edges and then click add seam you are defining the non connected point in the uv map.  generaly, make your seems in places that they wont be noticable.

7.  lighting techniquesd-  no tutorial can realy teach you that. its something that you learn with practice.  there are tutorials to show you stuff about how to work each light and turn on ao and stuff, but to get good results is a whole seperate feild.  lighting in the 3d world is alot like lighting in fashon photography.  nothing works like how you'd think it works.

-hope this helped
