set up of attribute grid, please help

i have downloaded attribute grid 1.1.1

i have 4 files but i believe i only copy 3 folders inot my root files.
is this true, if so can you tell me what the "language folder is for?

also i have noticed that there are no instructions on how to use the feature. does anyone know a good site where their is help with this.

i hope iv kept it simple enough! please any help would be greatly appreciated. Thanx! Aymen

Also does anyone have any working links to a store with an attributes grid, as i have no idea what the end result would look like.

i have two examples of what i am hoping for it to look like, please take a look and tell me if it is possible to achieve this with the attributes grid or do i need some thing else:

these two types of different listed product descriptions with color (dropdown) and QTY is what i am looking for. is this what the attribute grid addon is for or is there another way.

thank you once again you lot are great!
