who maybe haven't ever had a chance to raid before

I think rather than making this a complaint thread about what people aren't doing, it may be helpful (as the OP started doing) to share some tips for people who maybe haven't ever had a chance to raid before, including what sorts of gear or items they should expect to bring or even the types of buffs they should be ready to apply etc.

What are the types of things anyone should do to be prepared to Raid?
What types of items should they have ready to use in their bags?
Should they bring extra to share or is it every man/woman for themselves?
What are the best sort of buffs,wow gold spells, or even abilities that should be "must use"?
Etc.

Let's turn this into a helpful thread to guide people toward being successful in the Raid Finder.
