I think most of this advice is great for endgame players, but is kind of beyond a fresh level 40 player. I wouldn't worry about waiting for +10 warrior rings, they could be weeks or months away, upgrading whatever you have at the time helps a lot. Don't try to max level any of it, but throwing 10 junk items onto +4 warrior rings or defense bracelets will be a nice, and cheap, boost in power.
