This is all correct, and you should stream in what you think is best..
Still you should play a bit more with the settings. There are a lot of
options that you can use to make it also look good when you stream in "93"
and force it to 320x240.
You can also change the "93" to a custom setting!
Stop the stream, go to properties > compression > edit and select the 93
Kbps tab. Now you can change the "frame rate", "Video bit rate", "Video
smoothness" and so on..

Yes it's still to much. A dial-up will get "at his best" around 56kb/s.
128kb/s is about ISDN speed.
I do not know what your upload speed is, but it's no point using any
bit-rate higher that what it is.
(If you have a 512 kbit up the max you can put true it will be just under
512 kbit)

Yes the WMV7 codec (what I use) is for the "old" windows media player, and
will not force the users who are using the old WMP to 1st download a new
codec!
The performance of the WMV7 codec is a bit less than the new one, but it
will also take less CPU power of the system that you are using to stream.
