I believe current replacement spark plug for '97 2.3l is Motorcraft AGSF-32FM, this is a fine wire platinum plug
Autolite APP104 is also OK, fine wire platinum.
Any brand you want is fine, but Motorcraft and Autolite tend to last the longest in Ford engines
Don't forget to gap them, 0.044, they are usually 0.040 out of the box
Yes new spark plug wires are a good thing to do.
