What you did sounds about right.
If you look in the .qpf file, you should see that its a
text file, and contains statements something like:
set_global_assignment -name FAMILY CYCLONE
set_global_assignment -name DEVICE EP1C12Q240C8
set_global_assignment -name RESERVE_ALL_UNUSED_PINS "AS INPUT TRI-STATED"
(this is from a Tcl file for a different board, so your
family/device lines will be different).
The .qpf file is essentially a Tcl file used to configure
the quartus tool.

I never played with the opencores design, so sorry,
can't help there.
Cheers,
