Hi and welcome to our flock!
Glad you could join BYC! I would put both the feeder and the waterer outside of the actual hen house. I keep my chickens' feeder and waterer in their run all the time. When they are hungry or thirsty, they come out of the coop. They don't eat at night, anyways.
The waterer looks good to me, but the feeder might not be the best choice. It is the type of feeder that you'd usually use for young chicks. The older chickens may knock it over and will eat a lot of feed each day. You may want to get a hopper-style feeder, like this one:
11 lb Plastic Hanging Feeder
What are the dimensions of the henhouse (wood enclosed section) of the coop, and how large is the whole wire enclosure? Just looking at it, it looks small, but scale is hard to tell in photos. Each chicken should ideally have at least 4 square feet of inside space and 10 square feet of outside space (sometimes you can get by with less, but this is a good rule of thumb). Many pre-made coops that are sold are too small.
I would suggest using a bedding other than straw. Wood shavings are commonly used and I recommend them. Straw isn't as absorbent, unless it is chopped. It can be used in the nesting boxes, however. If you use wood shavings, a layer of 3 inches should be sufficient. It would probably need cleaning about once a week, but this varies. You'll have to observe it to see how dirty it gets.
Hope this answers some of your questions! Good luck with your future chickens. ISA Browns should be excellent layers and good pets for you.
