Sally, My suggestion is to get a repair manual if your going to work on your own vehicle. It's easy to get an inexpensive, high quality repair manual online. To be better prepared, read up on the job you're about to perform, it will show you component locations, bolt torque settings and what special tools you'll need. I would verify where the manifold is leaking first, because it could need a lower manifold gasket or a manifold as well.
