First off, what where the contents of the kit? You can get a good idea of the final product with the ingredients, generally.
As far as when you should bottle, give it roughly two weeks (others may disagree) and if you can use the plastic PET bottles, that way you avoid bottle bombs.
These days I only use my hydrometer as a rule of thumb. Some of the beers I have done lately have had OG's and FG's all over the place (within reason), so yea don't be to worried about the hydrometer, but do get a new one asap.
Have a merry christmas.
