Ola´ Francisco, nice to hear from you again,

Isn't the SUBGOAL tactical (see reference manual) what you need?
Something like

SUBGOAL (fn (t, i)=> REPEAT_DETERM_N (complexity t) your_tactic)

should do what you need...

I leave "b)" to someone else :-)

I think you mean that you are looking for a tactic that applies the
rule repeatedly until every occurrence of xRy has been used. You'd
have to write ML code to locate them and instantiate the rule
appropriately, e.g. calling res_inst_tac, since unguided rule
applications will always find the first occurrence of xRy.
