Found the emitters I like, too and they also have the picture tutorial showing how to install them. One of these for each of your pots should be plenty.

I haven't found any need for pressure compensators, although they come with some of the emitters. As long as you have good water pressure, you can regulate it by using the tap on the hose bib if needed.
