I've this twice on my car over the years, as well as on some others. Some things to note:
1) The oxygen sensor socket you can get in the MotorMite "HELP!" line of tools should be just fine, and it certainly ain't $18, either. Sears Craftsman also has the socket, as do others. The size is practically universal for O2 sensors on all cars so you will be using the socket again sooner or later.
2) The sensor wire unplugs via an in-line connector about 10" or so away from the sensor. The connector also has a clip on it to attach it to a bracket to keep the wire from touching the exhaust manifold.
3) It replaces from the top. You'll need a couple of socket extensions, but that'* all. You do _not_ need to remove the strut brace.
4) Make sure there is anti-seize compound on the threads. Both AC-Delco and Bosch units come pre-treated, if I remember right. If you have to add your own for some reason, make sure that it'* compatible with O2 sensors, and put the compound only on the sensor threads, not the hole threads. That way any excess compound will be pushed outwards as you install the sensor, not inwards into the manifold.
5) When you're done installing the new sensor (which will be all of about five minutes after you start removing the old one), don't be congratulating yourself so hard that you forget to plug in the wire from the new sensor.
