I'm not really sure what you are looking for in (1). Are you talking about streaming the data or logging it? It might be helpful to take a look at the SimpleAccel application ( http://tinyos.cvs.sourceforge.net/viewvc/tinyos/tinyos-2.x-contrib/shimmer/apps/SimpleAccel/) and the associated python script in the same folder.
There is an NTP implementation for the shimmer available in TinyOS version 1. Take a look at TestNTP ( http://tinyos.cvs.sourceforge.net/viewvc/tinyos/tinyos-1.x/contrib/handhelds/swtest/TestNTP/). However, I've never used this myself, so I'm not entirely sure how it works other than it uses the microIP stack for communication (take a look at the video here to see how to get this stack up and running: http://www.shimmer-research.com/research-2/microip-example). Also, you should know that version 1 of TinyOS is deprecated and shouldn't really be used for new projects. So you could either port this implementation to tinyos version 2 or else run NTP on the basestation (laptop or PC probably) and send the time to the shimmers any way you like.
