Can you run all three valves at once? Or at least the shower and hand shower at the same time?

Yes all 3 outlets can be used at once or any combination of the 3 can be used together or one at a time.

how easy is this for someone with limited hand use?

Very easy once the temp is set you only need to push the button you need.

What other items would need to be purchased to install this in a setup for a tub and a shower? Do the items come with installation instructions?

The rough-in in wall piece would be needed to have this work properly with a tub and shower set up. This additional piece would be the 35601000 Rapido Smartbox Universal Rough-in Box.

how much does the volume control change the water flow? is it 0-100% or a minor volume change?

Hello, the buttons are used for turning the water flow off and on. The volume adjustment is from EcoJoy to Full Flow. Specifically, as stated by Grohe: " SmartControl push for ON-OFF, turn for volume adjustment from EcoJoy to Full Flow " . Hope this helps! Thanks!
