I came across an article on safety when travelling, check it out:
http://tinostravelblog.wordpress.com/2010/10/28/dont-be-a-tacky-tourist/
It looks like its pretty helpful for first time travellers. Also Bookit.com has some good reviews with travel tips like how to carry money, what things not to wear or say etc. Read them at: Bookit.com Reviews
I hope it helps! Have a good trip. Where are you going?
