At least, the two last questions are clear !-:-) Christophe Jorssen have 
a similar problem for pst-circ2.  The solution is to write code for 
nodes in a token register and for components in another token register. 
  When the work is done, these register are called. Something like that:

loop
   Work and put something in registers
repeat
\the\register_node
\the\register_component

Hope this help.
