i need help with what items i should have

I need to know what are the best runes to have for a W/Mo that uses an axe. I got the best armor i just got no clue what to put in the armor. what upgrades and also a good axe i just cant find one. It sucks it does 6-28 cold dmg +14% dmg to hexed foes and +1 axe mastery. I just still do barley any thing.I also need a good farming area if any one knows any. so can any one help me with any of these. Also is there a way to reach black dye through mixing.

Runes - Superior Vigor (If you can afford/find one), Major / Superior Axe Mastery OR Absorption. Minor otherwise.

Don't know about the farming thing. Your axe doesn't sound too bad, go kill stuff until you find one you like better? Add some different mods?

As far as I know you can't get Black dye by mixing it, that's why black is a separate color in the game.

Hope this helps.

There is a collector axe 15% in stance, and a 15% while enchanted (both are 6-28), your axe is nice btw, cold dmg is nice.
I am using an ebon great axe of defense +15% in stance with Battlerage (which is a stance) on, and im very pleased by the dmg.
If you are going to use mending then use the 15% while enchanted, but i suggest you to go on with W/N, its a very very nice combo if you'll do pvp.

If you feel you lacking in dmg the problem isnt the axe (in your case), maybe you need more axe skills in bar, and less skills from your support job (just a guess), or maybe more points in STR and AXE.
Necro as support job is cool because it can be effective with only 3 points in curses.

My actual W/N setup is:
16 axe
13 str
3 curses

rez signet
plague touch
sprint
battlerage (E)
penetrating blow
executioner's strike
disrupting chop
bull's strike/power attack/protector's strike/rend enchantments

With this setup you want someone to smite/remove hexes off you (yay more dmg) and throw you just a few cures if needed, works very good with a smiter.

ps. forgive my english :>

As for black dye, you can only get them through drops or by buying them from the merchant (not a good idea seeing as he'll need your leg as a deposit). If it helps any, I've found more black dyes than anywhere else (including Pre-Searing) in the Charr-filled area not far from the Ruins of Surmia. Just explore around there. If nothing else, I also got a lot of runes from there. And it's easy-peasy to solo in.

all this might help
