If you have an automatic....check out the Super Chips Flashpaq....you can find it for around $275...it'll give you a boost via the transmission shift schedule, and allow you to change several other parameters (Octane specific tunes, and CRAWL / TOW tunes, fan speeds, tire sizes, lockers, DTC Codes, etc). Diablo also makes a great tuner, and I've heard good things about Bully Dog.
The K&N filters are high flow, but most complain that they let in too much dirt and are a hydrolocked engine waiting to happen. Many will also point out that CAIs offer little to no benefit over the stock intake. I decided to splurge on an Airaid XMP CAI with the prefilter sock, and am very happy with it. It uses the stock snorkel and the air filter is enclosed in a box...coupled with the prefilter I feel its just as good as the stock for water and dirt, while also a larger air intake. In about a month I've seen about a 1.5 mpg improvement.

Check this months JP Magazine re performance mods for JK. Most proved to be worthless. You'd be bucks ahead just getting it re-geared.

Contrary to popular belief, the only benefit to a CAI on a JK is the sound it makes - some people like that. Economically speaking, you're better off purchasing $200 of gas cards, you'll actually get mileage out of those.

As far as the chip is concerned, I don't have any experience in that particular type mentioned.

Proper regear is what you want if you'd like to drive your JK around like it had a big set of nuts - Chrysler geared the Wrangler from the factory for economy, not performance. Especially with bigger than stock tires.

Also depending on what you're going to do with your Jeep, the CAI can be a potential negative if you plan on doing any water crossings... Save the cash and put on a snorkel, buy power stickers, off road lights, rock rails, fuzzy dice, take your g/f to dinner...there are a thousand ways to better spend that cash.

Love my CAI. I installed an AFE kit, then sold it and went back to stock. Going back to stock was so painful that one week later I ordered an Airaid kit. It was like the Jeep was breathing through a straw again. Just fell on it's face. Throttle became jerky again. Needed more pedal to achieve the same acceleration. The Airaid kit fixed all that again...this time with the added protection of a fully enclosed air filter box.

The engine response is night and day. Power is much smoother and the Jeep gets up to speed with less throttle. It's noticeable with no dyno necessary. Fuel economy is unchanged. So don't buy it just for gas mileage. But the sound and added power and throttle feeling is worth every penny, plus you never have to buy an air filter again. Ever.

If you think about it, it's a much smarter mod than adding huge tires and lifts...because instead of losing money, you're actually gaining money over time as well as driveability.
