I think you're asking a two part question...

For the points you already have, it doesn't matter. It is what it is.

For the future: How many points do you earn per dollar?

EDIT: Looks like 1 point per dollar, according to the link above. That would make an airline redemption about 1.67% rebate on your spending. Not great.

There are links to some 2% cash back cards in the forums here, as well as cards with categories of spend as high as 5% cash back, plus plenty of cards that offer up to 3 airline miles per dollar - which can easily equate to 6% back.
