Ok, been looking over the pics u sent. IMO the 1st thing you need to do is farm crystals. Word on the street is crystal farming is best at floors 161-165 for new characters. I’ve tried it and got good results. The best crystal farming is at floor 500 for future reference (rarer crystal drops). You need lots of sapphires, angelite, & kyanite. Use them to put specific epic affixes on gear. Then use diamond to roll higher affix stats. As your character gains levels & better gear you’ll need ruby for legend affix.
I use these references when crafting gear:
Best advice I have based on your current gear is to use the legendary items with the poison element. Use a weapon that has as many of following affixes as possible +5000 weapon damage, % weapon damage, % elemental (poison) damage. If you focus on using your MH weapon primary skill look for items with (or add affix) extra attack & multi-attack affixes. Keep in mind that extra attack & multi-attack only affect your MH weapon’s primary skill (barrage, comet, blast, pierce), and not your OH primary skill or any special skills (meteor, twister, orb, storm). If you go with MH primary skill, add attack speed affixes which will annihilate mobs. If you focus on special skills use items with reduced cool down. Max the heroic skill for the skill you plan to use (ex, barrage) to 20 and then add +10 skill (+10 barrage) to two gears so you have +40 total skill.
Then add the following to various gear if you can, elemental critical (toxic), elemental critical damage (blight), critical damage, critical chance, crushing blow, and deadly strike. Use items with glasscannon, push the limit, or barbarian affixes. Be sure to have at least one +250 MP on hit affix.
Put all your stat points into power for now. The higher the floors you go, you are gonna die, no matter how much health you got. Hit them before they hit you (barrage + attack speed). Make a sanctuary mythic amulet as soon as possible to help reduce annoying deaths 
If you go with barrage, use a ring that has bewilder talent which will stun the mobs. You can try to spam barrage & stun them til they dead!
Once you start getting a lot of beryl & citrine you can create even more damage for your gear by changing the nature (of strength, of elements, of death), and talent (focus, amplify, empower, bewilder) on the item. You already have enough calcite to change the element on your gear to poison. If you go with a poison weapon, make all your gear poison via calcite, then when u got enough beryl change the nature to “of elements” or “of death” and watch your DPS increase nicely for the weapon skill you are focusing on in your build. I think you should try poison element with barrage + timewarp and see how much DPS you can generate. Try on different gears and compare DPS for the skill you primarily use.
Here’s some stat caps to keep in mind:
All procs 20%
Glasscannon 100%
Explosive 2000
Crit dmg 350%
Crit chance 60%
Crush blow 60%
Deadly strike 60%
Elemental Crit 40%

Dodge 60%

Purge 30%
Damage reduction No limit
Experience 200% socket

Gold 650% 850% ascend

Hope this helps get you started & makes farming a little easier.
