campbx allows you to do ACH to and from any U.S. bank account for $2. IAFCU is in Ohio, so you're golden. Bitstamp last i checked only allows wire transfers for USD.
CampBX hasn't enabled this feature yet. It's coming soon. You can only send outgoing ACH currently.
Bitstamp allows you to send outgoing SWIFT wire transfers. And yes, IAFCU should be able to receive these, just give their routing number + your account number. Though note they will likely charge you an incoming wire fee. Also note that they don't directly handle their incoming wires since they are just a small CU, but that shouldn't be an issue.
