I wired one last summer, by your discription it sounds a lot like the one I did. Invest in a realy good fish tape. Lighting is a real pain in the butt. Check your cans for sure, make sure they work before you leave the rough in.I did not have to run any thing in exposed conduit except for the in-line water heater,becouse the owner did not know were it was going to be located till time to finsh.Oh and get yourself a good chisel when time to put in the panel, if your going back to back with the meter & panel Them logs are about 8" thick.
