Check your owner's manual. Toyota does replace some of them for free at 80K miles.
I'm sure someone here can detail the procedure for checking to see if your's is bad or not. It's real simple on the '89s.
$120 sounds about right for the NAPA part, but I've heard of many people switching back to the OEM sensor for a variety of reasons.
17mpg is about right for a 2-ton vehicle with the 3.0. You might see some improvement with a new sensor, but don't expect to be breaking into the 20's.
