Most Lowe's and Home Depots will have what you need, most barb fittings will be with the sprinkler parts. Depending on how you set this up there may be a few other items you'll need.
savager....I'm right near east brunswick and lowes & home depot have a great assorment of hose barbs and the likes. You should be golden, finding them there.
I have some pics of the vinyl set up with the hose barbs here....
