I believe there's a limit of 1 WS gift card per transaction, so it might be annoying to use up all of your gift cards quickly. Obviously it depends on how often you fly WS and how expensive your tickets usually are.

The WS credit card doesn't require the ticket to be bought with the credit card - it just needs to be attached to your FF number when you fly.
