the way you are thinking about it is fundamentally wrong - $r is the
_current_ request object, so setting $r->param sets query string
arguments for the current request only.
you need to look into the Apache::URI module, which can be used to
create properly formed URI strings.

it won't - to create a self-referential URI use Apache::URI->parse($r)
