This looks like a great start. But I think you're starting from the  
bottom up. It might be useful to start from the top down. E.g., start  
with symptoms, then go on to causes, etc. Something like this:

   symptoms of problems on motes
     reboots -- how to figure out if this happened and why
     wedged nodes
     network not working at all
     network unreliable
     network performing poorly
   causes of problems on motes
     broken hw
     power problems
     stack overflow
     other ram corruption
     interrupts disabled too long
     tasks too long
     not using an interface properly
   how to debug on the motes
     leds
     serial printf
     jtag / gdb
   how to avoid motes as long as possible
     pointer to tossim docs
     pointer to avrora docs
   how to understand apps better
     how to look at global linking graph w/nesdoc
     how to look at app.c
   testbeds
     pointers to open testbeds
