a) module.pmod as file name is not very helpfull. Would it be possible to back-up one step in the directory tree when the node is module.pmod to get a sensible filename in the log?
Sure, modify interpret.c:do_trace_call().
b) Is there any tools around for parsing the trace output into some more readable format/graphs?
Not yet (AFAIK), but it shouldn't be that hard to do.
