Gaeilge ar an Ghrésán / Irish on the Internet
Just came accross an excellent site which gives a massive amount of links (over 800) to every sort of information regarding Irish culture and language, including poems and stories in Irish (some with translation), places to learn Irish, computer programs, internet resourses, placenames, Irish music, a Scotish Gaelic search engine, etc, etc. Féach ar: http://www.smo.uhi.ac.uk/gaeilge/gaeilge.html

A good site for Dublin place names in Irish: http://www.gaeltacabac.com/11.htm

This one is interesting for placenames in Ireland: http://www.logainm.ie/

Here you can find a list of all Irish books in print: http://www.litriocht.com/shop/product_info.php?products_id=5020
