Tony,
According to the owner's manual:
Fuel Tank is 19.55 gal...approx 2.1 left when idiot light comes on. My guage goes to about 7/8 when full.
I only got two keys, one round and one of the hex head/crest/lighted keys that was broken and had no crest. Both of these turned out to be master keys and worked in everything - ignition, glove box, cubbies. I have since ordered and cut two new lighted crest keys that work great.
I think the rolling pin thingy you're referring to is the counter weight that some people remove, and some don't...there are some threads on here about pros and cons.
I haven't had any luck getting a Genuine Porsche owners manual...I ended up getting one on eBay...they pop up from time to time.
