Oh, how the tables have tabled.

how does one change what the headers and links say?
example: changing the header text of "last blog entries" or "blurbs" or "contact" or the button inside of the contact container such as block, messages, etc
also wondering how to change the accent color of the music player from orange to something else.
thank you for your time.
