gates web site lists a full kit, for $50 at rockauto.com
really ask only one question:
how many miles are on those items. ( hard huh?)
all same?, all diff. ?
if you suspect all same ,then the pump must go. or it will fail before next belt is the logic of that.
the crank seal can be the biggest pain to swap.
the cam is easy ,even worse case.
also if you pull the big crank nut , then heat it so that you dont run the risk of
the last guy using locktite red,green or blue.
one guy here had that and he stripped the treads on the end of the crank.
CCW is the direction out (it is not left handed)
lefty loosey as they say.
no china pumps , ditto.
in fact I like oem new pumps. love them.
cant tell you how many early fails seen on rebuilts. (some are ok, but which?)
the oem belt might be mitusbishi but you did say year.
your list are all prime suppliers. all good.
my page is worse case:
timing belt swap
follow the link and at bottom is the dedicated 16v timing belt page.
Heads up:
your engine is interference so dont crank the crank with belt off , less , you loosing all the valve.
