I know there is an ability called "Wife's Stare of Death" that some will encounter early on. I think it requires a mix of frost, fire, and shadow resist.
This is a lie, there is no way to reduce the "Wife's Stare of Death" via armor, or magic resistances. It is 100% undispellable once locked on, but can be avoided by pre-emptively purchasing "Gift Box of Magical Shoes and Purses" and activating the trap outside the raid.
You've no doubt gathered plenty of trinkets. My recommendation is using one solid healing trinket, preferably Ashtongue Talisman of Valor and one solid DPS trinket (this includes SBV trinkets). Only use a timed healing trinket such as Spyglass of the Hidden Fleet if you are confident you can switch it out with DPS trinkets regularly w/o forgetting. If you've got a major potion stockpile or you're leveling w/ a healer, or if you don't have good healing trinkets, switch to two straight DPS trinkets should work for everything, including tanking.
Btw, I've been online since beta is up finishing out my own quests, so you've got a delay of about an hour here before I get back to this. We do have a podcast we recorded last night as well. Stay tuned.
I keep reading conflicting things about dailies giving XP. Can anyone confirm/deny?
No one can confirm or deny until WotLK is live.
I can say without a doubt that I purposely picked some dailies, turned them in and got experience for them in Beta. We have no idea what will happen live until live hits. The conflicting reports you hear are probably people citing that they didn't give experience when TBC came out. So in Beta, you got EXP, but no one has any clue for live.
