Stick with one campaign. Don't rush into things. Begin by conducting market research, then carefully pick three products. Review them on a landing page, add a few bonuses for buyers, and send traffic to it. For best results, set up an autoresponder as well to collect e-mails. It sounds like you're a newbie. You should probably have a read of my affiliate marketing basics course (soon to be removed) before you do anything. Note that the course is totally free; I don't even want an opt-in.
I would stick with one campaign as well and cherry pick your keywords. If you don't have access to Wordtracker then just use their free service: http://freekeywords.wordtracker.com/ Make sure you're bidding on keywords where there is at least some competition and concentrate on your Ad Copy. You need to know there is money in the market and then you need to work on your CTR so you don't get slapped by Google. Take things slowly!
