I know I need the ParkTool FR-2 for to actually remove the cassette but I don’t know what the tool is called I need for the bearing race (the two tiny holes).

Why do you want to disassemble the freehub?
The sprockets do look nice but I would replace before disassembly. Although a punch would have it open. No idea on the thread direction. Good luck
You know you are supposed to grease or wax the inside of a chain right? You re not meant to grease the cassette.
It looks like someone has already tried to disassemble it. Are you planning on serviceing it while it’s still mounted on the wheel?
Before you want to remove something, clean that dirty cassette first
And the tool yon need is called Pin Spanner im not sure, but i think the spa-1 would fit.
Maybe a 2 pin adjustable spanner wrench would work
You need a pin spanner. Park Tools, among others, makes a couple of types of these that would work for you. You can use the the adjustable pin on certain bottom brackets and heaadsets but that type is more expensive.
There a bunch a videos on youtube on how to repair or overhaul freewheels.

You need a pin spanner, something like the SPA-2.
Good luck – you’ll get probably 2 attempts to get it off. If the tool slips the first time, there’ll probably enough material to have another go. The second time the tool slips, the pin holes will likely be so damaged you’ll have to get a drill out.
A pin wrench. Park make adjustable ones. There is some evidence prior butchery here on one of the pins. Don’t be tempted to use a punch and a hammer.
But first please clean it up. Brake cleaner is good.
Check out this video for help. The ring you’re trying to remove is probably a left hand thread.

In the video he comments that replacing the bearings in their races is tedious. I disagree on this point, as I have akways found this part of the process quite exciting. Especially when a bearing pops out the tweesers.
Get organised and make sure your workplace is tidy.
Both of your freewheels need different tools.
