If you're going the crafted gear route, make sure to check mogboard(3rd party site) or at least world visit around to see if you can find cheaper. Even cheaper, if you know a crafter, materials are generally half price, or less.
Also spend your mendacity tomes on accessories to get some "free" ilvls, probably genesis too, you should get a few from doing dungeons. It's nice to run every dungeon even the ones not in the MSQ once, for the bonus.
For crafted gear if you're not buying the full set, priority should be the weapon, it's the most annoying to upgrade and the largest upgrade(relevant for the solo content, especially since some of it can be a bit challenging when underlvled in SB MSQs).
