I don't believe Philae has thrusters, much less thrusters that can be fired gently. I get the impression that there is one single-use thruster that was meant to counter the reaction of firing the harpoons, and neither went off as planned. I would guess that at some point they will attempt to manually fire both. But if something goes wrong with that attempt it's very possible that Philae will get launched off of the comet, so they probably want to get as much science done as possible before they even try it.
The bigger problem is the lack of sunlight on the solar cells.
