No outriggers. They will hang on stuff and swamp you. Class two rapids are pretty gentle. You shouldn't even need floatation. While I disagree that a 12' boat is too big for two people, the knee pad suggestion is right on--I use a closed cell foam kneepad--they are much softer than the rubber ones and don't scar the boat but they don't last all that long.
Another solution is to glue a neoprene backed strip of foam to the area your knees will be resting.
Class 3 and above, I wouldn't go out without floatation--center, bow and stern. When you dump, it displaces water and makes the canoe float high.
As to the crack--it depends--on a glass boat, in stress areas, I would use the full fiberglass patching kits--it is not hard to learn, but your first results will be less than aesthetic so I would take it to a marina or outfitting shop for the repair.
If you want a boat that will last and is dang near invincible, look into ABS canoes rather than glass/kevlar. A bit heavier, but worth it.
This is a very nice boat--16 foot, good handling. You will see that whitewater SOLO boats run about 12'. Best of luck--it's a blast.
