Posted this before but don't remember thr responses. 800 Sq Ft Shop/Metal 15 ft ceiling What is the best lighting?? John

Hello guys,today i took a small project. Have a older home ranch style about 1,200 square feet 3 bedrooms 1 bath 1 living room hall way kitchen mud room / Laundry room. 100 AMP service with about 12 slots. So i took a ride to home depote and pick up some outlets to replace all the ones in my house as they where all 2 hole with now ground conextion, so i figure i run a extra outlet to one the rooms that i needed for a tv / dvd player, so i find a junction box in the attic that was going to use for this extra outlet i was going to install , so i proced to shut the breaker off to get an idea on what is running thru this junction to my suprised to find out that this junction box ran most of the darn house here is what on this line this is all on a 15 AMP breaker--- 3 outlets to 1 room, 1 out side light, 1 Laundry room light, 1 hallway light, 1 bathroom light and exuast fan, 1 kitchen stove which is gas but has light in the oven, 1 stove hood exuast fan, 1 attic light, 1 attic fan, 2 bedroom 52" cieling fans w/ lights, 1 outlet in room two, and 1 outlet in room three. Needless to say i did not install the extra outlet i needed. Will half to do some rewiring here, so i am trying to figure out how may outlets i can wire together. All i have to work with is a crawl space and a crawl space attic, would be a good idea to run a new junction box to run cieling fans and lights if so how many can i put on one circuit. Need some input here. Thanks Ice199 :wall:
