Getting a podcast visible in Itunes

After setting up my blog mvplifestyle.com/blog so that I am able to post audio interviews I would like to figure out how or what precise steps I must take so that it will become compatible with itunes. I have spent a long time trying to unsucessfully use Feedforall. I would appreciate the advice of someone who has already done this successfully. I am using version 2.0 of WordPress on a mac portable and seem to be turning around in circles while trying to figure this out. I am not very handy with html, xml, php or any other programing language.

Thanks
John
