Okay…answer time:
Part A: There is a button that puts the currently selected material sphere to libarary (called put to library). That will put them into the library. Then, go into the library and SAVE it. Once you’ve done that, you can go back to the material editor and juss erase those spheres. The object will retain the texture (as long as you make a new texture entirly) and you cna then use that sphere for anotehr texture. Then, to reimport a texture, either open it from teh library or do a “From scene…” for the texture selection.
Double-sided texture: Okay, I’d recommand you convert the object to an editiable mesh, and assign each part of the mesh a SelectionID (at the bottom of the modify panel). Then make a Multi/Sub-object texture. Texture number one will correspond to Selection ID one, Texture number two on the mutlti-subobject will correspond to Selection ID two. That should get ya going there…worst comes to worst, make a plane and use a double sided texture as far as signs go.
OmniLighting: There is an intensity setting on the omni lights. In the lights and cameras tab, there is a lgiht lister. THat lets you set the settings for all your lights. it is your friend, use it. lol
