where can I get a copy of the installation sheet?

Instructions and product info are available on Grohe site

Does this item also include the part that you hook up the water supply too that's attached inside the shower wall? Thanks.

I don't know of any drop elbow fittings that aren't female, therefore you DO need a nipple to connect this UNLESS you have found another non standard method like a male adapter. The depth of your drop elbow from the finished wall dictates the nipple length. A drop elbow is used because it can be screwed to a backing allowing the nipple to be tightened without the pipe twisting or turning.

Is there a Starlight Chrome Grohe version in metal?

no, only plastic, but good quality I reckon. I had doubt, but it holds its shape and coating amazingly well (about 9 years long now)
