I have a list of some buffs for my gear (not sure how these things scale though), computed with landsoul's sheet.

Group buffs:
Enhance shaman (with Imp totems and Unleashed rage): +19.6%
Battle shout (Talented + Solarian): +13.5%
WF+Str totem (not improved): +9.7
Battle shout: +8.7%
Agi+Str totem: +7.5% (was actually a bit surprised that agi was this good)
LoTP: +4.8%
FI: +3.2%
Imp. Sanctity aura: +2.1%
Raid buffs
CoR (fully debuffed, low armor boss, using low amounts of gear ArP): +6.5%
CoR (fully debuffed, high armor boss, using low amounts of gear ArP): +5.8%
Blood frenzy: +4.3 %
Imp. SoTC (Retri pala): +3.0%
Imp. Faerie fire (Moonkin): +1.5% (if above 9% hit)

Numbers are of course uncertain, but the order of importance should be fairly constant with upscaling (my gear is a mixture of S3/T5/kara gear). There are probably some buffs missing, but I think most important ones should be there?
