I agree 100% with Prism. Make sure the scrim side is toward the backing so you're working "with" the batting, not against it. That also puts the 'softer' side towards the top for a better look. Sharp needles are always a good thing, too. :)

Time for a new needle?? That usually takes care of my problems

Yes, I've had that problem, even with a new needle, when using dark backings. I was unable to remove it with tape/roller/tweezers. I will use black batting from now on when I have a dark backing. I've also decided to try other battings for that reason.
