A few suggestions from a technical stand point of an audio professional
Wind screens are a must for sibilance and plosives and will cut down on the pops and smacks when you breath in and talk more often then not
and normalize the audio
You can use programs like audacity or if you got the scratch get Adobe Audition and learn to use a process called dynamics processing but there is a freeware program called Levelator i think which does pretty much the same job
The thing will set you apart from other podcasts is production value

and quality
A good uni directional mic with a good frequency response is what you should aim for that is either USB or XLR and run either digitally into your program or via a digital audio board.
