What is the difference between this unit and the eth-sp?

The eth-sp2 is an improved version of the original eth-sp.

Will this protect outdoor CAT5e cable from lightning?

Properly installed these should reduce and in some cases eliminate equipment damage from various high-voltage atmospheric situations including lightning. But lightning and wiring and lightning rods and other protection equipment is complicated and should be properly designed and installed to protect critical systems, and these gas-discharge-based units are one good component in a design. Ubiquiti probably has good design materials. These units are an inexpensive way to improve protection, but don't be fooled... Nothing will save typical outdoor WiFi gear from a direct strike, but these can help keep the damage from going further than that. Be sure to use shielded network cable with shielded connectors and ensure the connectors and cable shield are robustly connected -- sometimes the little ground wires break off.

How do you know when the surge is no longer working?

When it won't pass an Ethernet signal. The ESP circuit sacrifices it self when it suppresses the surge.
