I think KingAirFun really nailed it.
Kfahmi, look at our company 10-7 pages for ORD. This will tell you what gates we park at, and also what's expected for Inbound/Outbound operations as far as setting up the radios and that sort of thing. There are also expected (aka "Standard") taxi routes in the Jepps that are pretty accurate.
I haven't been to ORD in awhile, but feel free to send me a PM and I'll help you out however I can.
