Wanting to replace Moen Shower Trim Kit. No clue what I'm really doing.

[Camarsh]

I'm trying to do something nice for my dad and update his shower fixtures. I know it's a Moen kit that is currently on it and I know I have to stick with Moen. But I've never really messed with anything like this before. My question is, how do I determine which model I need to get?

I have pictures attached of the current set up but beware, everything is older and dirty. I'm looking at something like MOEN Banbury Single-Handle 1-Spray Tub & Shower Faucet in Mediterranean Bronze 82910BRB
But I don't think he'd like the shower head very much but who knows.

Looking for something like an oil rubbed bronze because all of the other fixtures like shower bar, and sink faucet and drain are all oil rubbed bronze.

Can someone help point me into the right direction so I can make sure I can get the right fit?

You have a Posi-Temp valve in the wall and 1/2" copper for the tub spout.
The 822910BRB comes with an IP tub spout and the rough-in valve which you already have.
You need the trim only and for a slip spout, not IP.
