To do a rib stitch, just knit the knits and purl the purls. In the beginning few rows, though, it might be hard to see. So a rule to remember is--whatever stitch you ended the row with, begin the row with the opposite stitch.
For a purl, you just have to make sure the yarn is hanging in front of the work, so it is in front of your right needle. Make sure you don't wrap it around the shaft of the needle or you'll get an extra stitch.
