[icecast] ices2 and Icecast2 on debian configuration question

Hi there,

I have a Debian sarge 512 MB RAM machine with icecast2 and ices2 that I 
installed via aptitude.  I have a 3MBit/s download and 800KBit/s upload 
link.

I would like to configure icecast2 and ices2 properly.

Here is my situation:
1)I have a dtdns address omac.darktech.org
2)icecast2 and ices2 on port 8000 would be fine.
3)I simply want to broadcast my 6 year old niece's voice which I have 
converted to .ogg using the blade encoder.
i.e. bladeenc elyse4.wav elyse4.ogg
3.3)I don't seem to need a relay since I am running both icecast2 and 
ices2 on the same machine.
4)I ran ices2 ices-playlist.xml
5)I ran icecast2 -c icecast.xml
6)I went to my brother's machine who uses another internet provider and 
uses a windows ME box(non-techie guy).  I did 
http://omac.darktech.org:8000/elyse4.ogg
7)Instead of delivering elyse4.ogg as a stream, it seemed to deliver the 
entire file before it played it in winamp.
8)I didn't quite configure everything properly because I was unsure as 
to what the playlist.txt file should contain.  I guessed and only placed 
"elyse4.ogg" in it.

Questions:
1)What do I have to change in my ices2 and icecast2 configs in order for 
it to stream instead of doing a complete file transfer?
2)What is the execution order for ices2 and icecast2.  Should I start 
ices2 first and then icecast2 or do icecast2 first and then ices2 
second?  I am guessing it should be icecast2 first but the documentation 
does not seem to tell me that.
3)Since I am running both ices2 and icecast2 on the same machine, do I 
still need a user password for ices2 and icecast2 to communicate to each 
other?
4)Considering my 800KBit/s upload bandwidth, what would be the 
recommended maximum number of listeners that I could stream? I am 
guessing that 800Kbit/64= 12...roughly twelve 64Kbit streams.  Is this 
the correct method or is there more that I should consider here?  I am 
guessing there is but it's best to ask right?

Thanks for taking the time to help.

Here are my icecast2 and ices2 xml config files:

different

multiple
             independent servers, and b) encoding/reencoding to multiple
             bitrates.
             If one instance fails (for example, the associated server goes
             down, etc), the others will continue to function correctly.
             This example defines two instances as two mountpoints on the
             same server.  -->

                 control how often it tries to reconnect, and how many times
                 it tries to reconnect. Delay is in seconds.
                 If you set reconnectattempts to -1, it will continue
                 indefinately. Suggest setting reconnectdelay to a large 
value
                 if you do this.

                 basically lets you control how much data gets buffered 
before
                 ices decides it can't send to the server fast enough, and
                 either shuts down or flushes the queue (dropping the data)
                 and continues.
