In talking with WotC cust serv, being referred to WotC Legal, and then to Andy Smith a while ago, the answers I got to questions about converting and OGC was that you can use names of creatures and spells, just not individual names as OGC, just as was done in the srd. So the spell Bigby's Feeling Fingers fropm the Greyhawk Adventures book can be made into an OGC spell Feeling Fingers.
