I think my ignition switch is beginning to fail. The engine has shut down twice now while driving and by jostling the switch engine turns on again. I am planning to replace the switch. How difficult is it to replace? Will I be able to use my current keys?

 

There are two bolts that have a rounded head that will be tough to remove. These are security bolts.

You only have to replace the electrical part of the ignition switch, not the mechanical part, so you key will work.

There are a few youtube videos out there. This is one that shows how to remove the shear bolts. This is on a 97, but the 98 will be similar.
