I think you have things covered. The PC industry is in a constant state of flux, but the resolutions which are most common are 1280x800, 1920x1080, and 1920x1200. The 1280x800 and 1920x1200 resolutions are popular for business projectors because they will work with either 16:10 or 16:9 screens just fine. That is, 1280x720 is the common 16:9 format derivative of 1280x800, and 1920x1080 (1080p) is the common 16:9 format derivative of 1920x1200.

While many computers are using 16:10 screens, others are using 16:9, and it's fine to use either type of screen, but it is truly obvious that PCs and TVs have gone widescreen (16:9/16:10 typically) and that 4:3 televisions of days gone by are in the past.

For a screen, you have a number of choices, but a tab-tensioned, motorized screen will give the longest life span if you want to hide the screen away when not in use. DaLite makes a nice positive gain grey screen which is good called high contrast cinema vision. It keeps contrast high with some ambient light while still keeping the image punchy. It is reasonably priced for the quality associated with it and I believe is available with quiet motors.

Things you haven't touched on:
What do you plan to use these for? I mean, really think about it.

Many churches use projectors to show lyrics. But, that's a pretty minimalist way to do things. What about having camera connectivity? The ability to show videos or TV shows? I assume that sound is all taken care of in the space, but how will that connect with the video feeds of the system?

Most of all, if someone needs to do a simple youth group 'movie night' setup, has there been consideration to a control system which can be turned on/off with a couple of button presses easily instead of needing full knowledge of the entire system?

Accessibility to projectors matters as there will be a need to swap lamps from time to time. Dual lamp projectors offer greater reliability in this regard since a single failed lamp doesn't bring down the entire presentation.

Make sure that screens are positioned such that lights don't fall directly on the screen, or that any lights near the screen can be turned off when the projector is powered on and the screen drops.

Yes, video to the projector needs to be considered. There are video over cat-5/6 solutions out there (HDBaseT). These solutions should NOT be confused with video over Ethernet which is completely different, and doesn't compare.

There are typically people who know how to install certain items, but care should be taken to follow all legal building codes with installation and purchases. A good electrician helping you out will go a long way, but A/V is not electrical and has some unique considerations.
