Do I need to shut off the water supply before removing just the diverter valve in a three-handle shower installation? Or can I just leave the hot and cold faucets turned off and pull the diverter?

No need to shut off the main valve. The diverter is after the hot and cold shower valves.

Are you referring to the main? If yes, then no. All you need to do is turn off the hot and cold valves on the lines to the shower. If that's what you were referring, then yes.

Follow the pipes from the tub as far back to determine if there are shut off valves on those single lines. If not, then you're only choice is to shut off from the main, unless by chance, there are valves that shut off sections which the tub may be a part. If you need to use the main and plan to have it off for an extended period of time, then I suggest you use this opportunity to install valves on each pipe (hot and cold) to the tub, then turn on the main with the two new valves both turned off to do your replacement/repair.

Cutoff valves are a good suggestion!
Unfortunately though, the fiberglass one-piece tub/shower enclosure water supply pipes go down to a really nasty and very difficult to access dirt crawl space. The floor joists and pipes there vary from about two to 14 feet above the hard-pack dirt.
If it comes to valve installation, it's going to be 1-800-PLUMBER ;-)

There is no need to shut off the main if all he's working on is the diverter valve. The diverter is AFTER the two faucet valves.
unless by chance, there are valves that shut off
Just sounds like extra work for little gain to me.
