Angelus, no. It multiplies whatever Defense you currently have instead of adding a direct 9% (if maxed). I have about 12.58% Defense Rate, so a maxed Angelus would bring me up to 13.71% (a whopping 1.13% more damage reduction).
For a tank with 50% Defense Rate, it would bring them up to 54.5%.
Archangel, yes. Your healing is based on your magic power. Maxed Archangel boosts your magic by 25%, thereby boosting all of your heals and DoTs by 25%.
Meditatio isn't bad, but it's generally agreed that leveling other skills would give you more impact. If there's something else you'd rather put into your build, then sure, it's a mistake. Otherwise, it's not going to kill you (or your party) if you have it.
Sanct, I recommend either Lv.1 or Lv.5. Lv.1 suffices for raids since it's needed for the max HP boost when casted with Aspersio (and the healing is enough in conjunction with Sorc AoE heals, which should be there if you need to be casting Sanc). Lv.4-5 has fantastic healing ability though.
Lv.2-3 is kinda.. enh. If you're just using it on a regular party of five members, then your regular combination of HoTs and heals can outheal it. It's still okay for saving time in healing a raid of ten members though.
