Lachobba, I don't know if the Pro-Silway or Wireworld are shielded. Many interconnects are not. I'm sure their websites would say, but this is actually a red herring.
My system doesn't even require a phono cable. Many high end tonearms include a hard-wired cable, so don't spend big money on one until you're sure you're going to need it.
The source-first argument applies here too: the world's best phono cable can't improve a signal. I doubt either of your existing cables would hinder the music as much as your present source components. This is also what Psychicanimal is saying, in his inimitable way. :)
