Yes, you do need to finish both Grizzleheim and Wintertusk. You can get a spell in Grizzleheim at Mirkholm Keep (level 35), and another spell in Wintertusk at Sudrilund (level 55). When you have those two spells, then you will be called to get the missing spells from Avalon.
You can also get some pets that you are missing. Keep going through Wintertusk to Nordrilund, and you will get a pet for level 58. Then you will be called to get another pet for level 78.
In order to get Detonate AND your new minion, Sir Lamorak, you have to already have Power Link. Unfortunately, yes you WILL have to do Wintertusk before you can get any of these 3 spells. You MUST have unlocked Sudrilund (third area of WT) and completed that quest before you will get a notification that you can learn your level 55 Power Link Spell. Once you have it, then you should be able to fight Sir Agravaine for Detonate and then head to Zafaria for your new minion.
In order to get Backdraft, you have to have Detonate.
Click the link to Power Link above to see what your requirements, prerequisites, and quests will be for each spell.
Complete quest given by Fanna Yellowknife (Owl Reagent Vendor in High Road).
Now, to unlock the quest, you will have to venture all the way back to Wintertusk and complete a series of pre-requisite quests to finally unlock this one named above. You will have to complete Wintertusk up to at least Nodrilund (second to last area in Wintertusk). Doing this will unlock a series of quest (first given to you by Erik Wyrdrune in Northguard. He will pop up to the right of your screen when he's ready for a quest for you.
So, complete Grizzleheim and Wintertusk to start gaining access to the quests and thereby the spells.
Since you're a level 82 Pyrommancer, it shouldn't be too difficult.
