@wlkanos , I'll second that; no point bothering with sub-CP160 gear, but if you have to craft something, craft Julianos until then, it's a good workhorse set.

You'll probably want to use more ground DoTs than you run now. Blockade is powerful. Twisting path is great to have too. While you're getting hang of things, you can refresh those two in a single batch with Crippling Grasp (best take this morph instead of Debilitate, but it's not crucial). After you have laid down those, you can just do Swallow Soul (with light attacks) while keeping up Siphoning Attacks and Merciless, shoot bow whenever ready, and when target is below 25% health, just switch from Swallow Soul to Impale.

Also, if you have sustain troubles while you're practicing rotation, switch to Atronach mundus, losing damage buff from other mundus is better than having to stop your rotation mid-parse because you're out of magicka. Absob Magicka glyph on your back bar's staff (make it infused for best result) is an awesome sustain source (it will proc off your blockade regardless of which bar you're on, and blockade should be always on the ground). And of course, while practicing, slot Elemental Drain and don't forget to keep refreshing it when it runs out, it's both sustain and added damage.

P.S.: Also, important note: I've just noticed from the screenshot that you have same enchantment (in this case fire) on both bars. It's a bad thing, because same enchantments share same cooldown, so if Blockade triggered your fire glyph from back bar staff, your front bar fire glyph also goes on cooldown - no benefit of having weapons with same enchantment type; it's true for all glyphs. Try absorb magicka back and either fire or spell damage front.

@wlkanos , gear won't make or break your build, really. ^^ And by all means, do use both Blockade and Twisting Path together, both are powerful damage skills, and Blockade will proc your back bar glyph all the time (twice a second if infused say, fire or absorb) even on front bar, it's crucial. As for having more sustain, it's helpful if you want to practice full light attack rotation - something you'll eventually want to be doing either way.

You don't need gold gear man(most of my characters walk in purple+golden weapons), also don't feel down even of your DPS is low after 160 CP, since you get more attributes up till 300 CP (and your damage as a magblade scales from max Magicka as well). I wouldn't recommend spring loaded infusion since you get nothing out of the stamina part of it, if you don't feel like magicka recovery try finding blue food of max Magicka+health.(bloody Mara can work if you need one which is for all levels). I would aim for a consistent 18k on a dummy with 160 CP and proper gear(purple +golden weapons with 2 sets and another monster set).

PS: funny thing that only me and John answered, since I know him in game.
