You are good to go. Did you get a reloading manual? Either the Lyman Cast #3 that was posted or the 50th Reloading? You really need to understand the process before you start.
What you have is more than enough. Ignore the scale, you measure Pyrodex by volume anyway. It's density is very different than that of BP. I'm assuming you have a BP measure with BP equivalent marks. If you fill the cartridge case to the base of the bullet how much equivalent BP is that? I'm guessing you can fill that case with Pyrodex but you want to verify that. I'm not sure but I think the 32 S&W was loaded with 8gr BP? You might want to verify that and see how much a case full of Pyrodex measures in a BP measure.
