Series resistance seems paradoxical, no?
You do it like this -- inside the feedback loop.
Ferrite beads aren't much impedance compared to ESD, and saturate quickly besides, but yes, that's a help, especially around bipolar circuits like TL431s (if that's the sort of thing you were thinking). Chokes work best with caps -- don't exceed the C-load limit of the amp, or, more generally, avoid the region of instability for the device (e.g., TL431 is okay for C < 10nF or whatever, and >4uF or whatever).
The above circuit also works well for dealing with C-load while keeping the active device happy: note the out-to-in cap.
Also also, note that TL431 is basically an opamp with a horrendous (but suspiciously stable) input offset voltage, unidirectional output (it can only pull down, not push up), and +in tied to GND internally as it were. Other refs vary (the LM4040 series is similar, but "PNP", i.e., referenced to the more-positive voltage node, AFAIK; a lot of fancier (REFxxx, AD, LT) parts have sense inputs that basically generalize this even further), but the same method applies.
