IIRC, it's similar to Carrara interface:
[menu] Windows -> Texture to get the texture/shader room.
Then click on 'shaders' tab in the window on the bottom right corner of the screen. Each of your materials should have a shader listed w/ the name of the material that you assigned in Wings; double click on one.
That will open the shader window. Change the values in the shader sections. I can't remember what shader options Basics has... basic, I guess. Color, highlight, shininess, bump, so on.

As for .avi, change file formats in the Render Room -> Output tab.

Friends don't let friends use booleans.
