You need to be 50 to start the quest, though technically a level 50+ toon can summon Stanos for you, but it's touch & go as to whether a sub-50 toon can complete the handins (I've heard he'll eat handins from under-levelled toons). Just get to 50 if you want to be safe.
The General has dropped ONE Quill that I know of on AK, so start farming robes early and often instead.
You'll need the General's Pouch, JDD, and Quill to complete the quest. Little else really matters. A reliable walkthrough I've used can be found HERE.
I start with the pickpocketing of notes, and go from there.
Hope that helps.
I did this PC side Pre-Luclin on my Rogue and was using Ragebringer at 48. I started working on the quest at 40 (pickpocketing the items, etc). I might have had it sooner, but leveled on my way to finish the quest. Of course, that was PC side, but it was an era before the time EQMac is frozen in.
