Well, first of all, there should never be a need for an "emergency transfer", since it doesn't really matter if the lid seals or not. Some people don't even use lids. You can set the lid on loosely, and never see an airlock bubble, and it'll be perfectly fine. But anyway, it's too late now to stop you from transferring!
What's the recipe? If it's underhopped, it'll be sweet no matter what.
1. I don't know. I never heard of anybody doing that before, but you probably had enough yeast in suspension to keep fermentation going.
2. No. Pacman is a workhorse, and usually full attenuates.
