Does anyone know of a method to export a 140 record FileMaker Pro v.7 list into the Mac's Address Book Version 4.0.2 (475) - vCard file?

Yes buy this thread plugin or brew your own. But you have to observe that the Addressbook uses an dynamic field structure ...but you could utilize embedded applescripts to accomplish it:

tell application "Address Book" 

set foo to make new person at the end of the people with properties {first name:"Søren", last name:"Dyhr", company:true, organization:"Lydtekniker Søren Dyhr"} 

make new email at end of foo's emails with properties {label:"work", value:"[email protected]"} 

make new address at end of foo's addresses with properties {label:"work", street:"Axelhøj 23c", zip:"2610", city:"Rødovre", country:"Danmark"} 

make new phone at end of foo's phones with properties {label:"work", value:"40423223"} 

save addressbook 

end tell 

Now this only put my data in you 'book, but this is the form - then you have to think of ways to loop thru all the filemaker records.

But easier solutions exists:
