To sniff IP and MAC addresses, you need to be "on" the wireless network in the first place, which can be done if you use no wireless security, or weak WEP security. That's why I'd recommend using WPA encryption instead, if you can. Unless you have the WPA key, it's like having the cable unplugged - sniffing tricks aren't possible. I could never say it's perfectly secure - that would be daft - but I'm not aware of any exploitable holes.
