You should definetly include monk under "ignore DR/magic" and that ToM weapon enchantment under "ignore DR/any". Maybe make a hint at illusions, that several of them are mind-affecting (I'm not sure how many).
Freedom of Movement can be gained by Heart of Water (CM spell) and that one ring from DMG.
Sneak Attack Undead/Construct: Deathstrike Bracers should be mentioned and the level 3 rogue ACF. Those are the biggest ones to ignore sneak attacking immunities.
Ignore Incorporal: Serren Material (BoED) for 4k and maybe could be done at level 1 with Hidden Talent: Psionic Minor Creation.
Immunity to stunning is gained by Elemental Body (level 7 hour/level buff).
Ignore illusions: Since almost all of them are magical effects: Arcane Sight. Also Beguilers from Shining South get Trueseeing for free.
