>> mix audio feeds via MP3s within RSS.

Here's an example RSS feed for audiocasts:
http://www.SQLSummit.com/Channels/SQLSummitTechTalkAudio.xml

You use the <enclosure> tag and include only MP3s if you're specifically looking
at a podcast audience. For example:

<item>
<title>SQL:2003 (SQL/XML) and the Future of SQL</title>
<description>Oracle standards architect, Jim Melton, editor of the international
SQL standard, discusses SQL:2003 and the fusion of XQuery with SQL. Length
6:13.</description>
<link> http://www.SQLSummit.com/People/JMelton.htm</link>
<enclosure url="http://www.SQLSummit.com/Multimedia/JimMelton.mp3"
length="984360" type="audio/mpeg" />
</item>

>> Are there various methods to accomplish the mixture of the sound and XML

Not sure what you mean by "the mixture of the sound and XML" but

1. You can use SMIL to synchronize a multimedia presentation that includes MP3
audio.
Example:

2. If you're coding for Windows Media Player, you can create XML-encoded
playlists for audio (and video). The playlists and Windows audio files are not
iPod compatible.

>> Would one platform be considered better than another (Apache/Linux, Mac,
Win)?

RSS and MP3 are platform-neutral.

>> Has anyone ever heard of a best practices relative to podcasting? Would there
be such a thing as an "industrial-strength" podcast server?

BitTorrent gets a lot of hype:
