It depends on whether or not you want to stay a pure or not. If you want to stay as a pure, follow the others' advice. If not, then train Attack to a high level. Not much point in training Defence if you're gonna miss.
I would stay at those stats, you have a nice barrows pure there. However, if you decide to level up more, you should definitely get your defence up first rather than attack. The higher your defence, the more options that are available to you.
