The first week of Soldiery tomes is about to end and I, like most people, will have already capped. But I don't know where I should begin with my upgrades.

At some point this week I'll be getting allagan belt, pants and book to get my SMN to i91, but should I cap tomes this coming week and purchase the weathered Evenstar body piece? Or wait until the week after and purchase the Weathered book of Spades first? Or should I forget both pieces for now and go for accessories first for accuracy?
