I must have grabbed my 3.0 PHB (which I still keep out) when I last looked at cloudkill. My bad.
Shield provides a force shield effect, which makes sense since that's what the spell is *supposed* to be. So it protects against incorporeal touch attacks, though, granted, not all of them. And the "shield" bonus type is one that a wizard rarely can fill up, so it is useful in that way. So I'd call it useful, but not great. I think a "greater shield" (3rd level or so) that has the same effects but mage armor's duration would be more useful and not unbalanced.
Identify is both more and less useful. Sure, you get all the info, but on only one item. I've never understood the outrageous cost of the spell. It's a very silly and pointless attempt at game balance. I never use the cost, myself. But having a high-level loremaster in the party helps. They get identify as an Extraordinary power, so they don't have to pay the gp cost. Greater Lore, 6th level ability. No gp cost, no number of uses per day. Use it before WotC nerfs it!
Baleful Polymorph goes back to the original intent of Polymorph Other -- you turn your enemy into a frog, and then you step on them. However, it removes the uses of Polymorph Other that evolved in the game since its inception. That's why I think a Greater Baleful Polymorph is a good idea -- so you can turn the guy into a walrus on the ladder. Lovely, evil idea that, that violates neither the letter nor the spirit of the spell.
