2.) I made a image I like to put on the glass (Information), and I like to put it on the glass, and I like the image to be see through. How can I do this.
3.) Lighting: No matter how many times I use lighting. I always pounder on this one question. "Map Size". Ok..'256, 512...what ever the number is given when we click on a light. lets say we make one light (Spotlight, infinite), will give us a texture problem from the lighting. Increase this, say to 2048 or 3000. Will give a good render of textures, but the waiting is....well..a long time. Will 4 Spotlights of 512 give a light value all together of 2048 to speed up the render? OR are they individual lighting taken a value of their own? Why is it such a problem..thinking..g's..of a system I have 2GB of DDram (PC3200's at 400mhz duel channel) and AMD athlon 3200XP+ 2.20Ghz. I would think when rendering and seeing this scale "Rendering Shadow Map" would speed up. How can I make this go faster with the same values.

I would suggest downloading Ajax's free materials pack from the free stuff area and looking at the glass materials in there (because I know they work :D) If you want proper glass you will have to use raytracing, I usually find raytracing the shadows is easier than using maps as well, with your system it shouldn't be a problem.

As for the lighting question:
Shadow maps are individual to each light. You can't add them together for several lights. The shadow map size defines the resolution of the shadows for that particular light. You can have one light with a map size of 1024, giving a very sharp and precise shadow, together with another light with a map size of 256, giving a fuzzy shadow, in the same scene. The shadows from each light will be different according to the map size.

A light shadow map size of 64 gives a good diffuse shadow effect like a dull day.
