Mister beer keg might be a little big for a starter...you could step it up into one, I suppose, starting with a small bottle, jar or flask. You wouldn't need to step it up that big unless you're making a big beer or a lager.
And yes, I usually use light, pilsner or wheat extract, depending on what type of beer I'm making.
