Nathan. I had a look at your lists and pictures. My suggestion would be to do the first one or two gigs with a good AV company and see what equipment they use and if you are happy with the results buy exactly the same equipment. The company will be only to happy sell you the gear. Another route would be to hire a freelance technical director and get him to make you a list. I am not familiar with some of the gear that you have specified so it would be useless for me to comment.
Your pictures seem to be of a very small room but you mentioned audiences of 200. I would make your equipment list and purchases based on that number then you can scale down the gear for smaller audiences. You may even need two screens.
A few comments powered speakers are not the routes I would go, try a sound set up with out board amps, Crest and EAW come to mind.
Your control booth should be at the back of the room so that your sound guy can hear what
