> If a 64bit workstation connects to a Firebird server running on a 32bit server, can the workstation use the 64bit version of fbclient, or must it use the 32bit version?

No.

32-bit or 64-bit client library depends on the Firebird client
application. If you have a 32-bit client application, then use the
32-bit Firebird client. If it is a 64-bit client application, then go
with the 64-bit Firebird client.
