Hi Scott, It has been a while since I have used printf (in TinyOS), but I'm fairly certain that your problem is that there is framing around the (active message) packets coming from the serial port that is causing the "extraneous" characters.
The printf instructions ( http://docs.tinyos.net/tinywiki/index.php/The_TinyOS_printf_Library) mentions using a java app, PrintfClient ( http://code.google.com/p/tinyos-main/source/browse/trunk/support/sdk/java/net/tinyos/tools/PrintfClient.java), which handles this framing.
