How can I add an audio file and flash player to my blog

Normally, you'll need to upload the audio file to a file storage site like archive.org or box.net.  During class you can upload files to JeffLebow.net/ttp-files.

To add a flash player for the audio, you'll need to create a new post, select 'Edit Html' and use this code:

<embed flashvars="audioUrl=MP3_FILE_URL" height="22" quality="best" src="http://www.google.com/reader/ui/3523697345-audio-player.swf" type="application/x-shockwave-flash" width="400"></embed>

(replacing 'MP3_FILE_URL' with the URL of your audio file)
