Shadow Priest craftables advice.

[Conno]

So my shadow priest is coming up to 80, and I just want to make sure i'm getting the right craftables,

leggings of woven death, http://www.wowhead.com/item=49891
deathfrost boots, http://www.wowhead.com/item=49890

are they the best choices for a shadow priest? if not possibly some suggestions would be grand.

Basically, yes.

what about things like sandals of consecration, i'm still not entirely sure on the benefit of spirit to a shadow priest, I was told to gear it like my fire mage, crit, hit, sp.

Hit>SP>Haste>Crit>Spi>Int
Could post a PP list but I'm too lazy.

Edit: I'll try to dig something out of my mind. These are most likely not 100% correct.
Hit: 1,7
SP: 1
Haste: 0.98
Crit: 0.8
Spi: 0.59

Spirit gives us a decent chunk of spell power from Twisted Faith and Improved Spirit Tap procs, but overall, it is still something you do not want to stack over spell power, haste and crit.

Useful posts, they are appreciated. Don't want to make the mistake I made on my mage and buy the wrong craftables.
