Figure out what build you wanna run first.
For either build, your armor is OK, but you're not getting as much out of it because your AR is a bit low.
For SNS, you need to hit IAS/CC requirements to become more functional. You're currently at 1.595APS and 33CC. You need at least 2.31APS and around 50CC. 2.51APS is doable so long as you can keep your CC high enough (around 55~60CC) but I personally run the 2.73APS break point with around 53CC (which is on the low side) for better freezing.
After you figure out what APS break point you want to run and you achieve it, put everything else into AR/armor/life.
For Archon, just go as much black damage as you can (weapons with no elemental damage, for rings/amulets, look for +min/max damage) with high CC/CD. There really is no requirement on each value, but the higher the better.
