If you're noobish, then stick to the basics. Get yourself a $20 headset mic and free copy of Audacity. And then play around with them. Don't worry about mixers, pop stoppers, and other such rigamarole. Just get the bare minium you need to start, and start. Once you get the hang of it, have a few episodes under your belt, and feel you have a good idea of what kind of podcast you want, then you should get equipment to facilitate that. But if you're just starting out, don't make it harder than you have too.
Equipment is fun and exciting, but you don't need much to start. And some of it might not be nessary (you aren't going to need a mixer, for example, if your only imput is one mic) Save your money for when you have a better idea of what you want to do.
