How do I convert all of the image files to .PNG's, and once I do have them in an editable form, how do I get them to be used by the game client? Is there something I will have to download to do this?

You should be able to use TerrariaTexturePack and a rarfile of converted stock images (all the XNB files pre-converted over to PNG) from here. If for some reason you'd rather, this tool can extract the individual PNG files from each XNB. For reference, TerrariaTexturePack is the tool which allows Terraria to use your custom PNGs, and it's impossible to convert back to XNB (a proprietary, game-specific format created by XNA Game Studio).
