You'll probably get this answer lots, but..
Without a doubt, the best reference you'll get is the game itself. Within the character museum, there's the ability to move the camera to view the character at any angle. I know this is what I used to complete my Tira outfit, I literally left the game running and fiddled with the camera as needed.
For the sword and shield, be sure to check out the sword thread
for some help. I would also suggest looking around for any tutorials or advice on Link's sword and shield from Zelda...since it is about the same style.
Good luck, and don't forget to check out the Soul Calibur thread
