Replacing the oxygen sensor is a fairly simple job.  You have two oxygen sensors, however.  You'll need more information to determine which sensor is needed.  You'll need to know the diagnostic trouble code so you can figure out what it means, or you'll need the shop to tell you which sensor is faulty.

The front sensor is in the manifold, and you'll need a special oxygen sensor socket or wrench to replace it.  The tool will have a slot or opening in one side for the wire to be fed through.  

The rear sensor is in the front exhaust pipe under the car.  Removal is simple with an open-end 22mm wrench.

Many people have reported poor luck with finding aftermarket manuals for Hyundai products.  You can purchase the factory manuals at the dealer, but they'll be expensive.  You'll probably get the most benefit from the information at www.hmaservice.com.  You'll need to register for a free account, and the site requires internet explorer.  It'll give you access to the factory repair manuals, schematics, and technical service bulletins.

I'd be most interested in finding out the trouble code.  Oxygen sensor failures do happen, but there are other problems which people often misdiagnose as an oxygen sensor problem.
