You do not need to replace the valve. The tub spout has the diverter built into itself. Mixed hot and cold water from the valve will go down into the tub spout until you pull up the diverter knob on the tub spout which blocks the water flow and forces the water to exit through the shower head.
The tub spout is entirely separate from the valve. The 3 holes you see in the valve are the inlet ports for the hot and cold water and the exit port from the valve for the hot and cold "mixed" water. If you are going to replace the valve it is the entire thing you replace. All the way to the 1/2" threaded copper pipes that go into each of the 4 sides of the valve.
If you do not plan on replacing the valve then the next steps would be to repair the line to the tub spout. Then make sure you can find replacement trims for the valve- unless you are going to reuse the old trims in which case you are all good.

r/Plumbing on Reddit: Replacing bathtub faucet and whole shower head
September 26, 2020 -
So I will preface this by saying I’m an idiot and know almost nothing about plumbing. So long story short I broke the cartridge in my shower handle, was able to get the cartridge but not the handle (cartridge stuck in handle and won’t come out) so plumber told me $1800 to replace the entire shower/bathtub combo. For $75 I found the exact fixture I have but in bronze not silver. How big of a project is it to replace the faucet and shower head so they are all bronze? Does that entail opening the wall etc? I’m hoping I saved myself some money here, if not I’m just doing a bronze handle with silver everything else

You can change everything on the shower side of the valve wall without opening the back wall. The only time you'll need to open the wall is to change out the valve entirely. His quote was to replace the entire valve, which does require the wall to be open in the front or back, usually the back because the shower wall is on the front.
