General RTOS questions not related directly to ChibiOS can be easily found online. A good answer to your question can be found here:

http://stackoverflow.com/questions/2410 ... use-of-thi

Regarding the question about function declaration, I think both will do the same for ChibiOS but the second one (static THD_FUNCTION(Thread1, arg)) is prefered now because it's compatible with NIL. At least that's what I remember from head...
