Hi Judi!
I'm new to paphs. too.

From what I know, they are like other orchids, choose the pot to fit the root mass. I think it was very smart to uncover those lower leaves.

That would have likely led to rot.
As for mediums, mine is in a mix of fine bark and perlite and seems to be doing fine. Although I think i might need to water a bit more. Unlike many beginning gardeners and orchid growers I tend to underwater more than overwater. I'm just weird.

I think any fine but well draining orchid medium would work fine, just remember that paphs like more water than epiphytes!
Hopefully a more experienced grower will chime in on this.
