I have to ask--how is this a "rescue" if she knows nothing about the animal? I'd call it a "transfer."
At least she's seeking information, though; more than most people do.
Is this an animal she caught, found in her house, or was given by someone? With the little information you've provided, it's hard to say if it's a juvenile of a larger species, or a full-grown adult; or if it's a US native or something else.
If we're talking US native, have her compare her lizard to these:
Texas Banded Gecko
San Diego Banded Gecko
If it looks an awful lot like these, then that's probably what it is.
As far as the heat pad goes, that's not necessarily a Bad Thing; I'm assuming it's not physically in the tank with the gecko but rather underneath. Make sure it's not under the entire tank (i.e. have one end with no heating, so the lizard can find a "happy medium" somewhere between full heat and no heat).
Provide a small standing water supply (I use bottle caps the size of the ones on V-8 or CranGrape bottles), and also mist occasionally.
Other than that, the care sheets she's looking for will be dependent on the outcome of the ID.
