One way to make the job easier is to have P::RD bless each node in
your parse tree
(look up "Autotrees" in the module documentation or take a look at
demo_LaTeXish.pl
and demo_eval.pl that come with the module). Then you create methods
in each of the
node classes, and let them work out the tree traversal themselves.

Yes, it should be.

I tend to use Data::Dumper myself.

Glad you're finding it useful.
