Also, look through some Google search results (maybe type in the model of your linksys to see if someone else has the same router + airport?):

Joining an existing wireless network shouldn't be a problem, if you're only interested in sharing a printer and/or using the audio features. If this is what you're after, read AirPort Express: How to join an existing wireless network in client mode.

Extending a network is another beast, if you're interested in that check out geerlingguy's links, it's a good post.
