You should be fine so don't worry. If you don't see any activity after ~27 hours give it a good swirl and shake to get the yeast in suspension. If you aren't getting any activity in your airlock immediately after shaking then warm it up to 66 or 67 and it should take off. If all else fails...
Good summary aiptasia.
You can leave a standard gravity ale sitting on the yeast cake for 4-5 weeks and you won't get any off flavors from autolysis. So don't worry if you don't get to bottling right away.... just don't wait too long because you will need some health yeast left in suspension...
