Pitch Circle Diameter or Bolt Circle Diameter. Same thing. I'd use BCD myself.
In answer to your question, yes, but you don't need to, 9 speed ones will work fine.

Just use the 9 speed rings they are fine

unless they are brand new 9spd chainrings, a 10spd chain will probably fit on them just fine. I've been running a sram 1051 10 spd chain on a set of 10-15 year old LX cranks with (possibly) 8 spd rings on them, obviously they have a bit of wear, but chain seems happy enough, no chain suck and shifts flawlessly.
