Do you plan to do Coils? If so, go for jewelery pieces with Myth and just go DL everything else. Once you get the Allagan Chest, get the Myth helmet; Allagan helm does not drop until Turn 5.

If not, I'd actually recommend aiming for Chest/Helm first, then Legs/Feet second, followed by Gloves, Jewelry slots, then +1.

I don't recommend going Relic +1 right away, it's not worth it as it only gives +5 vit, +4 str, and +2 damage. You can get way more out of other items than you can Relic +1.
