Go with 128-bit WEP. BritBen is quite sophisticated, unlike the vast majority of those who would call themselves "hackers" (who even give the bad guys a bad name), so using what's available will repel most of these "script kiddies" and their ilk. Setting it up between a Linksys access point and an AirPort system isn't even really difficult, though you need to put "$" in front of the hexidecimal characters if you copy them from the Linksys settings to the AirPort settings; this tells the AirPort system to interpret the characters as hex, and without it the characters are interpreted as plain text.
Darien mentioned restricting your wireless network to specific MAC addresses-great idea. You set this up using the configuration software that came with the router/access point-I think you can do it through its HTML interface, just like the rest of its setup.
Zone Alarm is good if you're both paranoid and an experienced network geek. It will tell you of every instance of an outside request, ping, etc. The logs get to be really long, and they don't do you a lot of good if you don't mess with the router every day. I haven't checked lately, but I don't think that these tools are in a Mac format.
On the Linksys router settings you should tell it to block outside requests (unless you're trying to host games, etc., but I don't think you are), and let the built in Network Address Translation (NAT) give you a bit more camoflage from the outside.
Finally, make sure you have a good antivirus program on each computer you use. There aren't as many bugs that hurt Macs as there are that hurt Windows (and even Linux is getting hit nowadays), but protect yourself, just the same.
Enjoy!
