Yeah, as babalu said, warming it up will help. Since you're not planning to do anything with it for a while, I'd get it up to the low 70s and let it go for a week and see if you get a drop in gravity.
If you're worried about getting viable yeast in each bottle, I would make sure to pick some up with the racking cane when racking to a bottling bucket. It will mix in while you rack and give you some in each bottle, and you really don't need that much. If you're worried about viability though, you should add some fresh yeast at bottling.
