Which Shaman buffs to whom in a group?

[RaldoMcdaldo]

I would like to get some advice on how to buff when grouping with a shaman. I haven't been able to find specifics in any of the "guides" relative to 1999 so far (I've probably missed some posts, but if there is info. relating to this it certainly seems very limited). I do understand the basics of stats, but the details are what i need. I would like to know which buffs work best for the different classes in my group and some insight as to more common various situations (numbers, combos, etc.). Specific spell labels aren't so important, except for as an example, as I can do that breakdown in relation to my limited understanding of overall stats. If someone could just lay out their detailed style/pattern when grouping with a shaman, especially when it comes to buffing in general, that would be way more than I've read thus far. I would like to have a good starting base knowledge so that experience learning will be more efficient and less painful for myself and my group.
