Thank you for reporting.

It seems a bug of isboot. Your NIC is link down, but isboot never retry
on first connection. Because of this, it failed to find the boot device.

I have updated isboot and created 9.1-RC based image.
Please try it:

NO. You can use both iBFT software like gPXE and NIC's rom like Intel iSCSI 
boot agent.
The isboot should work with any NIC supported by FreeBSD.

If your NIC driver is within the kernel, you need only isboot_load="YES".

> 4) Is it likely to work (better) if I find an em(4) card instead?

I have tested with Intel cards/onboard. If you want the maximum performance,
I recommend you to use Intel card, but other cards should work with isboot.
