Perhaps you can explain this again, its a little unclear whether you are talking about which power supply to use, or something about pin configurations.
The board can be powered from USB. It can also be powered from an external power supply.
The CD-ROM image comes with a reference design containing all the pins on the board.
Terasic also have a pin generation tool (though I have not used it).
Cheers,
