Advice on making No Knead Jalapeno Cheaddar Bread--First Time

Any tips I need to know about adding cheese and/or jalapeno to the dough?

I have the Jim Lahey bread down pretty good, but my son just asked for cheese in the bread this time.

Couple of question;

I plan on cubing the sharp cheddar, when do I add it?  During the initial mix of everything or maybe after a turn or two?

Same thing on adding the jalapenos?

Can I bake in a loaf pan or should I use the cast iron pot?

Thanks!
