Map(s):
http://www.odci.gov/cia/publications/factbook/geos/tv.html This map gives a general overview of the islands as well as select economic and social facts.
http://members.nbci.com/janeresture/tuvalumaps/tuvalu.htm Although it's quite large, this map is very detailed.
http://members.nbci.com/_XMCM/janeresture/tuvalu2000/index.htm There are lots of pictures on this page, but the map near the top is excellent to get a general orientation of Tuvalu's relationship with neighboring island nations.
Individual island/island groups-these are very helpful for local specifics:

http://www.tbc.gov.bc.ca/cwgames/country/Tuvalu/tuvalu.html Just in case the above sites aren't working or are out of order (I've had trouble with them and they take a long time to load), try this page for another general (and manageable) map of Tuvalu.

General:
http://members.nbci.com/_XOOM/gray/janeresture/tuvalu/tuvalu.html This is a personal web page devoted to Tuvalu, but it is quite extensive. The information is salient and concise, providing historical, cultural, and tourist (including places to stay, where to eat, where to go shopping, what else to do, and how to get there) information. Everything is augmented with pictures and entertaining graphics. Don't miss the links at the bottom!
http://members.nbci.com/tuvaluonline/ Another site devoted to Tuvalu. According to David Stanley: "Everything you wanted to know about Tuvalu."
http://tuvalu.tv/ THE site for Tuvalu and the .tv domain name. You will find Links to Tuvalu news and photos (virtual tours).
http://www.tbc.gov.bc.ca/cwgames/country/Tuvalu/tuvalu2.html See the flag and words to the national anthem.

Photos:
http://members.nbci.com/_XMCM/janeresture/tuvalu2000/index.htm Lots of "contemporary" pictures from around Tuvalu.
Also, check the first three sites listed under "General."

Music:
http://www.tevaka.com/tevaka.html A contemporary band based in NZ but closely associated with Tuvalu. You can download short sound clips and buy the band's CDs and other merchandise.

There is information on Tuvalu out there. However, compared to other Pacific island countries, I've found that it is quite scattered. Many of the sites contain links, but few reference each other. So, make sure to check multiple pages if you don't find what you're looking for right away. The information about music and dance also seems to be less plentiful than other locations. I'm sure there are sites out there, though, and it may be worth an extended search.
