Change your belt to TWH.
It's going to shine when when the DPS is more than 150K DPS.

Change your pants to rare, with high INT & VIT + 2 sockets.

You can also try some other skills.
You can replace gargantuan with big bad voodoo/slam dance The reason is you don't need gargantuan to do damage.
Or you can try horrify/frightening aspect for armor boost.
Either an all-out offensive or defensive skill.
Both skills are good during elite fight (with arcane under your feet).

Passive skill, you can replace grave injustice with vision quest.
Both are good. Just choose one that works for you.

Depth digger pants are good. Good option.

12% MS is ok. You may need some time to get used to it (since you are used to fast MS on other heroes).
You can have more MS if you want.
If you need more MS, I'd suggest get MS from bracer i/o pants.
This is because you lose too many EHP if you use Inna's pants.
(Mana is still manageable with 1.18 attack speed. You just need to be careful with your left click/bears spamming).

I believe your current build is good enough up to MP8 solo.
Try Horrify/frightening aspect. Use horrify when your spirit walk is cooling down. Use spirit walk when horrify is cooling down. It will give you better survivability during elite/boss fight.
Try some key runs @ A1/A2/A3.

There's 2 option to increase mana regen for WD so Bear spamming wont result in OOM:
1) As Aleune pointed out .. use Vision Quest passive (take out Grave Injustice if u r not using BBV since at higher mp mobs die slower and medium CD skills such as SW, SH wont need GI passive) .. in between bear spam keep throwing at least 1 jar of spider so that VQ is always active.
2) Another viable alternative i just found out (but hv yet to test) is to use Rush of Essence passive instead of VQ & change Widowmakers to Spirit Barrage-The Spirit is Willing .. from what i read RoE stacks so its much better that VQ since ur other skills such as SW & SH also triggers RoE .. plus SB dmg is higher than Widowmaker ... Use Bears to clear large packs & when 1-2 mob left use SB.

Btw i prefer rare pants to get higher EHP bcos u can get high armor from it + double resist (physcl @ poison res is good choice). Once u hv high armor try use Horrify/FA n see how tanky u can be    playing higher mp 24% MS for WD is not important since mobs dont die that fast .. if u wanna speed farm lower mp, change Zuni Marrow to Tyreal Might to get that xtra 12% MS (the xtra dmg to demon n elite also helps clear low mp super fast).

Yes, the more the merrier.
The faster your attack, the more damage + more life you can recover.

Just some heads up on zdog build.

In terms of burst damage, zdog is better than zbears.
Based on my experience, zdog is not as effective because of the limitation in pushing up DPS.
You will hit a ceiling. It is very very very very very very difficult to push up the DPS for zdog build.

Few reasons, there are at least 3 gears are bound to zdog build (in order to have ZERO second cool down zdog).
It means less flexibility in upgrading your gears for more DPS.
Secondly, these MUST-have gears are rather low DPS gears. You just can't do much about it.
Thirdly, it is damn rare to get better replacement. It's either you can't find any gears better than your existing ones or you need to pay few billions for a piece of gear.

It is very difficult to push zdog build more than 135K DPS. It's an expensive build.
However, zbears can easily push more than 150K+ DPS, at half or 75% of the zdog cost.

Refer to my MP10 Ghom test,
95K DPS zdog VS 130K DPS zbear, zdog win. 
128K DPS zdog VS 150K DPS zbear, it's a tie.
My zdog build stuck VS 180K+ DPS zbear, zbear win by at least 20%
My zdog build stuck VS 200K+ DPS zbear, zbear win hands down.
(Note: Both builds use SoJ)

try out Spirit Barrage-The Soul is Willing + Rush of Essence passive for mana regen .. from my own personal testing this combo is better than widowmaker + VQ for mana regen .. reason being RoE is stackable with each skill that proc it eg if ure using SPirit Walk + Soul Harvest + SPirit Barrage .. thats 3 stacked = 3x49 mana over 10 sec + 44 mana per hit from The Soul is Willing
i even tried replacing Hex-Jinx with Mass Confusion-Paranoia (since both are crowd control & make mobs take xtra20% dmg) bcos MC also proc RoE. With Grave Injustice Passive i was able to spam all skills that proc RoE which make my mana pool rarely dip below 25% .. not forgetting Spirit Barrage has high %wpn dmg multiplier (almost same as bear for single target) compared to widowmaker %wpn dmg.

fe3doe wait for itemization patch to go 0zdog .. ilvl63 Homunculus 

  expensive bro ... I also scouting the gears for ZD but a bit hard to get.. easiest I think buying a set from another ZD WD..

Play Bat not syok ke bro? my 155k dps WD killing some MP10 elite faster than my barb, just SH (5 stacks)->MC->Hex->channeling Bat....they just dead

siapa ada zero dog set? nak pinjam pleaseeeeeeeeeee 

This is why I use bears in my skill setup.
I'll use bears when it knock me back.

To counter those fast running elites, use hex.
Turn it into pig and COB it. 

P/S Alternatively use plague bats.
