Would this have been a good spot to double barrel the turn? I may fold a Q or my opponent may be on diamonds and this way I'll get to showndown and win more monies.

Does it matter if my opponent is 20/15 or 30/5?

No, I don't like it. You have 3rd pair. I play same way you did.

You did fine. It makes no difference between the two stats you quoted. I doubt a 20/15 is limping UTG fwiw.
