Do I understand correctly that you can use the Action: part of this card to cheat this into play without paying its resource cost (and discarding two cards, ideally Elven-lights) in such quests as Escape from Dol Guldur where there's a limit of "one ally played per round for the whole group" similarly as you can cheat allies into play with Sneak Attack or with Elf-stone in the same way?
Yep spot on. You are putting the ally into play, not playing it. So you get around the play 1 ally per round limit. Note also you can use this action any action windows you like. Doesn't have to be in planning if you don't want to do it then.

Correct, the strength of the Jeweler is that he can jump in play for "free" in any Action Window (and yeah it bypasses the limit of Escape from Dol Guldur since he is put into play)
