out of interest why are you re-building it if it's only done 60k? I've seen zetecs hammered every day and are still going strong at over 100k. Things to look out for may be different depending on the circumstances before the rebuild. I'd just whip the sump off, check the bearings and replace if necessary, rocker cover off and check cams and tappets and note the condition of the oil. Should all give you a good clue to the health of the lump. But like I say, if the engine has had problems, then I wouldn't bother rebuilding it as a 1.8 from an xr3i or Si etc is cheaper to buy than all the rebuild parts and will drop straight in with an ecu swap.
the big hole on the block is an oil breather, the pulleys, 1 is a waterpump (you need that), one is a tensioner (you need that), one is PAS pump, you could do without that but it'll be harder to turn the wheel, or if you're putting the lump in a non PAS car then get rid of the pump and you need a shorter belt. you've got the alternator yeah, and the other is an idle pulley to get the belt going where it needs to go whilst getting plenty of surface area on the other pulleys.
