Phase Shifting, for a total ignoramus Options

[Dimora]

So I need to do some phase shifting for audio I've recorded with my Tascam US-122. I've read up a little bit on it, but considering I am a complete fledgling in this side of audio, I can't understand a good deal of it.

Are there any good begginer books on the basics of audio (wav components, filters, and all that good stuff that I don't know the terms for yet)?

Can anyone recommend software that will allow me to do phase correction?

Thanks!
