WotLK Raid leading

[LTUAcid]

Hello, could anyone give me some tips how to make a raid for Icc10,25 and Rs25. I have been making voa groups those are simple just take each class for 10 and for 25 try not to take more than 3 of each and thats it, but for loot distrubuting having some trouble because i have no addons for that. So I would appreciate any tips about composition (Like how many heals in 10/25 or what classes should i prioritise over which and such), addons for keeping track rolls or any which just helps with raid leading, or when ispecting a person what are the red flags and such.

RaidRoll is an addon that tracks rolls.
2 healers for 10 mans (sometimes 3), 5 healers for 25 man. This is purely the "default" expectation of healer amounts. E.g. VoA 25 should be easily doable with 4 heals even (not giving much credit to pugs, you never know).

General rule of raid comps:
Bring as many as buffs you can.
Class specific buffs:
Druids for GotW; Mages for Intellect; Paladins for BoK/BoM/BoW; Priests for Stamina/Spirit/Shadow Resistance; and so on.

Then there are spec specific buffs such as:
DK's:
Frost - 20% Melee Haste
Blood/Frost Hybrid tank: 10% AP, 20% Melee Haste
UDK: 13% Spell DMG

Warriors:
Battle Shout - 550 Attack Power
Commanding Shout - 2255 Max Health increase

Fury: 5% Crit

You get the idea.

Red flags?
Mixed gear. DPS with tank items, etc. (to boost GS)
Awful gemming / Bad gemming choices.
Weird 'my own' talent builds.
