Being Imperial I'm slightly disadvantaged on my magblade, but also running some of the current BiS so it balances it out.
Current setup is 5xTBS, 3xMoondancer jewelry, 2xGrothdarr and vMA inferno on each bar. Grothdarr is extremely good even on stage 7 since most mobs come to you and if not then you can go to them.
If you weren't able to access a lot of these, then you could run with 5xJulianos, 3xWillpower jewelry, 3xTorugs on head, shoulder and staves with an weapon/spell damage enchant on your front bar. Alternatively, 3xInfallible Aether jewelry would give a boost over Willpower and can be farmed in purple.
If you're familiar with the mechanics of vMA then you can get away with dual destro staff and applying dampen magicka on your back back for times like stage 4 boss, stage 5, stage 6 boss, stage 7 and stage 8 rounds 3 and 4. Otherwise I'd recommend resto staff for healing ward just to be on the safe side.
Also, although it's broken for weaving and a huge pain, using funnel health along with refreshing path solves all your healing problems including the crematorial guards in stage 9 providing you put your dots down, shield up and then funnel health. Most people fail at points like that because they naturally choke trying to heal themselves instead of counterintuitively using that healing to dps the adds.
I'd also suggest, if you're uncertain, using blur/mirage/double-take as it can help you survive better during tough fights like stage 5 or stage 7 round 3/4 otherwise use that slot for your rearming trap and the extra 12% boost to crit damage.
