Just the usual antivirus/antispyware with vista. I use AVG free, spybot, ad-aware 2007 and ccleaner and have had no problems. Firefox and itunes work fine, as do I'm lead to believe, Office 2000 onwards and openoffice. Any pitfalls? Make sure you get rid of all the junkware that most new pc's come with-click here could be useful! As for hints and tips, theres generally some good ones that appear in the vista forum and you can always ask in there if you need any (it helps get a more specific response). And one more thing, don't listen to people saying vista is rubbish go back to XP, having had vista for a year it's a joy to use, so ignore them! Enjoy your new purchase!
