For voice only podcasts, mono is usually preferred as you can achieve better sound quality with less data. The choice of mono/stereo depends on the type of podcast.

never do production work in MP3, instead work with a lossless format such as WAV, AIFF or FLAC and for final use then export to MP3. If you import an MP3 into Audacity, edit it then export it as an MP3, you will lose quality once in the original MP3 encoding of the imported audio, then again when you export it from Audacity as MP3.
