Cast iron question

I finally got a Lodge cast iron skillet that I want to start having fun with. I've never cooked anything on cast iron. I tried to find a video of someone using one on the egg but was unable to find one although I have seen some pics of people here using dutch ovens, so I have a few questions. When cooking breakfast items like pancakes and eggs, what temp do you usually want to maintain at the dome...350ish? Is there a preference in regards to direct or indirect? Do you usually keep the dome open when cooking items that need more attention with flipping or stirring or do you want to try and leave the dome closed as much as possible? Is there a max temp that the cast iron can withstand? Just want to know the basics before I start eggsperimenting. I appreciate all input!
