As far as the sugar goes... I would add that as soon as you have some kind of fermentation going (just incase you have to pour your batch).
First, you might want to check the specs on your yeast, it might take them a while to get going.
Furthermore, if -by the time you read this- there is no fermentation going I would give it a really good shake for a few minutes, just to put some more air in there. That usually get things churning.
If you still have no activity in a day or two, I would try re-pitching with some more yeast.
Hope that helps...
