Any kind of vacuum cap. Doesn't matter if you use the regular rubber ones or the plastic colored ones. No air will be running through it so it doesn't need a cap at all really, it just looks better.

The heater core, I would take the hoses off completely and put one back there that wont kink. Regular heater hose will work as long as they are not in a bind and can't be suck shut with a high volume water pump. Or you could go to the parts house and look on the wall for a U shaped preformed hose.

I bypasses the heater core yesterday...I just went to the harware store and got some fitting and put them together, worked real well, I'll have to get a pic and put it up.
