They have shims and loud is OK, if they get quiet that is bad that means they are tightening up and you might burn a valve. I've never heard of anyone needing to adjust them with even 300K miles on their engine.

I haven't even done my Timing belt yet!

It looks to be pretty involved but would probably be a good thing to do in conjunction with the timing belt as most of the access work would be done. Maybe at 180k instead of the the 90k service.

Inspecting the valve clearances is listed in the maintenance section of the FSM rather then repair so it is clear that Toyota recommends it on some kind of schedule. It also lists valve clearance problems as a cause of emissions failures.

These trucks engines have been making it to 200k without but maybe they'll need the clearances checked to go 300k in good working order.

If you do it yourself please write it up.
