I completed the quest myself a few days back, hence been unable to summon Andreg and complete the remaining quests.
I asked a friend of mine, who didn't start the quest yet, to do the quest with me.
We started a fellowship, and naturally, we began our trip from Amlan who gives the initial quest.
We visited all locations that triggers the quests, and each time, before picking the quests up himself, my friend told me there was a ring. Though I was not able to pick up these quests neither before or after my friend did it, and of course he was not able to share them ("<player> is ineligible for this quest").
There was no problem whatsoever for my friend to obtain all required quests when we knew how it worked and got the locations, but that didn't help me.
I followed my friend and his summoned Andreg very closely all the time but there was never a ring above Andreg or on the mini-map.
Conclusion:
If you have already completed the main-quest and lost your whistle, you can NOT use someone else's NPC to get the remaining quests for the deed.
P.S.
I have 3/7 for "Tracking an Old Goat" and I have done several more quests in the Gravenwood than the Gravenwood quest-deed requires, so "Tracking an Old Goat"-deed is not gating "Quests in the Gravenwood"-deed.
