The Transmit Power Control option on the AP: if I set it to manual to, say, 17dbm. Does that tell the client to reduce its power by 17dbm or to not go above 17dbm?

It tells the AP to set that radio to that power level.  17 in this example.  You are better off setting them in the radio profile as the max transmit power.  This way if 17 is too high and the AP wants to turn down the power it can.

I'm curious about this topic too. We have a pretty dense collection of APs (in adjacent classrooms). We've had to turn down power manually in a number of places because the Hive didn't always seem to figure out the best power levels when APs are set to automatic and in close proximity to others.

I realize there are no definitive best settings but it would be great to hear some suggestions or experiences.

Your best bet is to setup the maps (walls, doors, windows, etc) in HiveManager and see what your RSSI coverage looks like. To be on the safe side head to the site and see if your seeing the same in person. RSSI of 70 to 67 is the worse you want but I went for 50 within the classroom with 60 to 65 in the hallways as my bench mark.  I kept increasing the max channel power until I found what worked for me.  Mine was 12 I have double concrete walls to the hallway and drywall between the classrooms.  One row of 7 and one row of 6.  I originally followed supports advise and set them to 5 but that was way to low.  After some more research I found that 10 to 15 is the general range if you want to limit the AP to a classroom.  Also HiveManager just lowers power for coverage not density.  Its more worried about channel overlap than sticky clients not leaving another AP.  As always test test test.  What works for me might not work for you.
