Forgot transaction fee...

I think you could probably resign the transaction again and add a fee, although I don't think this is possible within blockchain client.. but can be done as far as im aware.

It'll be picked up eventually, but you'll have to be patient.  I'm not aware of any "easy" way to cancel or modify an unconfirmed transaction.
