Well, on first glance, you don't appear to be stacking a specific res + all res, but it looks like the majority of it is arcane, so maybe stick with this one, as at the moment, you aren't making the best of OwE. At the moment, you are at a very important milestone where bad choices in gear can result in you having to re-gear again later on.
If I were you, I would start looking at some of the legend sets, and how you may need to gear around them e.g. Inna's set lacks innate resistances, and all res costs a fortune on these pieces. I have found the issue with Nat's boots and ring to be a lack of Vit, or, in other words, how expensive Vit is on these pieces.
You also don't appear to have much in the way of life sustain. Life on hit will certainly help with increasing survivability so I would pick up some of that. Unity rings are quite good for some LoH, crit, avg dmg, and dex so maybe one of these? Consider switching to lifesteal only when you get close to the 90k - 100k dps mark, as the reduction in Inferno is quite a hit.
I like to try and keep defensive stats off rings and amulets if at all possible, as most of your dps output will come from these! Armor items should carry the most of your dex, vit, and all res.
