what's the difference between...
name-san
name-kun
name-chan
and just the name??
mm..i know that ...-san is for respect and older epople and such..but yeeaa..waah! lerning japanese on your own is hard... -__-''
-san is basically "Mr." or "Mrs." I believe, and generally used for people above or on the same level as you.
-kun is usually for males who are younger, but could also be around the same age as you. Most usually for high school level and below? Though there are exceptions. And in certain cases (such as a manager to his employees), kun can be used for females.
-chan is for young children, girls, and possibly friends if you feel like attaching the title.
-Just the name...is when you're extremely close and comfortable with that person; for example, your boyfriend/girlfriend when you've been together a while, or your best friend, etc. At this point, most people still use only the last name

I believe the first name only with nothing attached is..like the ultimate level of closeness?
I may not be 100% correct on those, but they're my current take on how to address people. And each of them have deviations from the general rule...you really have to get a feel for them from listening to how they're used, and then it gets pretty easy =)
Hope that helped a bit.
