Not too much of a problem.
You have to remove the airbag, steering wheel, collar trim, and the lower dash trim under the steering column (if equipped). I can't remember if you have to pull the lock cylinder or not to get off the passenger side of the trim, either way it's only 30 seconds of work to pull the cylinder. The tilt lever has evil loctite on it, so a pair of thin vicegrips work to loosen that(if you need to). A black magic marker covers up the scrapes on the black paint on the lever's base when you are done.
3 screws hold the clock spring in place. The airbag connectors all have internal grounds, so you don't have to worry about a random deployment.
Make sure your steering wheel is fairly centered before you remove the steering wheel, and don't remove the plastic "holder" from the center of the new clock spring until you are ready to install it. One connection to horn, one to airbag, one to cruise control (if switches on the wheel) and two connectors under the dash.
