Thanks... I need to know everything! Help!
I've been trying to learn since last August. My friend was trying to teach me... That didnt' go so well. He's out of practice and was guessing at a lot of words. After I came back to the States, I checked out a Pimsleur's Cantonese beginner course. I've completed it successfully, and I can proudly say I currently have enough broken language capabilities to get myself picked up in Hong Kong, and that's about it. Ever listened to a Pimsleur course? It was great for acclimating me to the tones of the language, but I had to take a break every two hours; I couldn't take the 'storyline' of the American businessman hitting on his young Chinese hotel clerk. So... I've turned myself loose on the internet, clicking around on this guy's link:
http://www.cantonese.sheik.co.uk and picking up slang off of these two:
http://www.unique.net/~yan/cantonese.html and
http://www.unique.net/allenwu/waycool.html .
Are you a native speaker or are you in the process of learning, too? I could use a lot of help, that's for sure. I'm not exactly living anywhere with a thriving Cantonese-speaking population to immerse myself in, although I'm thinking about doing some volunteer ESL tutoring again as a way to break into the small community that is here. Need to speak it if I'm ever going to learn it. And I need to get in the culture if I'm ever going to learn the conventions of etiquette that I'm stressing over... I don't like it when I don't know what's expected of me, you know? It's rough.

There are just a lot of amazing gaps in my knowledge right now... for instance, I know how to use "dann hei" as the conjunction "but", but I don't have any idea how to say "and." Please forgive my spelling... kind of a German phonetic transliteration going on... hope it's not too hard to make out.
How's that for a concise answer to your question! lol!
