newbie PS1 config question

[Ko Pu]

PS1 question:
How can I change the PS to display the current directory? According to 
documentation, the \w should show the current directory, but when I used it, 
it showed ~, what I'm looking for is to display info similar to pwd.

prompt question:
I'm using dsl modem, so the ip address is dynamic, and the prompt showed the 
ip address, how can I change it to my computer name? I added it to my 
/etc/host but I still got the ip address. This is what I have in my prompt.
