Personally I think you are using way too many arties. Your resists will be crap and your mods (sta, mana) won't reach what you want them to.
When I choose arties, I choose them because either of their intensity (Spirit of Totem), or they give me something unique in that particular equipment slot I couldn't otherwise have (Mace and Shield).
An example of a good arty to have: Mace and Shield gives you HLD on your mask, whcih frees up a mod on your bow for something important. Alternatively, keep HLD on your bow and have a huge chance for HLD to land. This is a good decision to use this arty.
Bad decision: Using Fey Legs. You can get DCI so many places, you get horrible resists, and don't get the opportunity to add LMC/Sta/Mana which you want on your template.
I'm not too impressed with RBG. It offers MR3, LMC 15, and 10 Mana.. but then poor resists. You could easily imbue MR2, LMC 8, 8 mana, 8 STA, and better resists on an imbued tunic.
In conclusion some arties are "transitional arties" which you pick up while you are building your character before you actually build and imbue a suit. Stuff like Fey Legs or RBG are good for this. When you finally imbue your suit however you will want to take the less is more approach so you can reach your goals of 150 or 180+ sta, along with tons of mana.
I would go with:
Head: M&S, or Spirit of Totem
Hands: Stormgrip
Talisman: Conj Trinket (with Primer of Arms, Vermin Talisman, etc available as swapin)
That leaves these spots open and imbuable:
Neck
Chest
Legs
Arms
With this many imbuable slots you should be able to tweak to get to 180 sta, have tons of mana, close to 40 LMC, badass resists - and even overcap some (like fire/poison) in case you get corpse skinned.
Depending on spec you may want to run Orny on your bracer, or just have 2 imbued jewels. Alternatively, go with Navery Night Eyes on your head, and 2 imbued jewels with FC1 - if you plan on needing casting ability for chiv, necro, myst, mage (depends on your template)
Lower Mana Costs (20% or 40%, 39% is just as good as 20% for a bushido user)
Miner, can you clarify this statement? Why is there no difference between 39 and 20% LMC for a bush user - is that due to the way the game rounds #s? (20% LMC = 4 mana LS..)
Personally, I'd keep the quivers, the extra damage you get helps (IMO) more than the 5% swing speed increase.
Lastly, must the quiver be worn to get teh 10% damage bonus, or merely in your pack?
