1. You can "sniff" for WiFi signals for free with a simple program called "Network Stumbler":

2. I've seen these really cheap pens that blink a light when they detect transmissions in the 2.4 Ghz range. They were originally designed for cordless phones, but you may be able to hack one for longer range / more sensitivity, if you can find one.
