Any tips/tricks to get this handle off? I don't want to snap anything inside.
Water leaking heavily out of shower head, suspect something inside buggered out.

Googled "Perfect Match" logo on the screw cover...Danco brand? Am I going to need a special stem removal tool or something?

Once the phillips screws out it pulls straight out.
Going to have to shut off the main and drain the line before removing the the rest.

Sorry...I wasn't very clear on my OP...I did get the cover off and the screw out (1st pic)...it's stuck on pretty good. I would like to get some block leverage behind the handle and the wall, just not sure if that is good idea.

Shoot some of your favorite lube on the rear, let it sit, and tapa tapa. It should come right off

It's going to be hard to get off.
Wiggle it and tug real hard pulling straight out, not going to hurt anything.
Any Lowe's or HD has pullers if this does not work.
Just replace the screw leaving it out about 1/4" and use that to center the tip of the puller.

Master Plumber makes a faucet handle puller for about $5.00 at Home Depot. Look for it in with the other Master Plumber stuff. If you take the screw down to any place that sells fasteners, they should be able to give you a hex cap screw with the same thread. You can put the center prong of the puller into that hex and apply pressure to the handle only; NOT the ceramic tiling behind the handle.

Clean the corrosion up with some phosphoric acid (toilet bowl cleaner is often a dilute solution of phosphoric acid), and next time use an anti-seize compound between the handle and the stem of the faucet.

I've taken many of these handles off and the handles don't always survive. Sometimes they are heavily corroded and seized onto the valve stem. Replacement handles are about $6 though so it's not a huge deal replacing them. It appears the one you have is too small anyways. It looks like it is for a faucet but someone threw it on a shower stem. The shower handles are normally deeper and cover the exposed threads.

I try to put a rag on the handles and tap them in various locations to free them up. After I hold the back and put straight forward (sometimes rocking it back and forth).

Your stem looks like a standard Price Pfister stem you can get easily too. Just remember to check the stem seat after you pull it out. The washer might be trashed and putting in a new washer will only work temporarily if the seat it sits on is chipped or damaged.
