Some additional clarification on lifesteal and spellvamp:
True damage, on-hit procs (even ability-based, such as Kog'Maw's Bio-Arcane Barrage) do not benefit from lifesteal or spellvamp. On-next-attack modifiers (such as Nasus' Siphoning Strike) benefit from lifesteal.
Spellvamp is only 33% as effective if the ability being used is AoE. Certain abilities do not follow this rule.
I'm not entirely sure on this one, but I believe abilities that do physical damage benefit from spellvamp (but not lifesteal).
