Second rising? Refrigerate dough?

2 questions: 1. After filling and rolling it up, should I let it sit to rise again (as with challah) or put it straight into the oven? 2. I'm thinking of making the dough ahead of time and refrigerating it to bake later: Would that work? If so, should I put it in the fridge before or after filling and rolling? Thanks for sharing this recipe. Looks great!
