Answer 1

This method can be found in following files:
grep 'reloadPrice:' . -rsn
./js/varien/configurable.js:271: reloadPrice: function()
./js/varien/product.js:463: reloadPrice: function()
./skin/frontend/base/default/js/bundle.js:83: reloadPrice: function()

Answer 2

For change custom option value, you should change in to js/varient/product.js
and in that page you found, reload:function()
that function call at the time of on change event.
Good Luck

I also had the issue of having to change the default behaviour of Magento on this one. I included jQuery in my project and I finaly figured it out by first removing the default behavior of Magento and instead on calculatePrice call my calculatePrices()-function:
$j('#select_20, #select_21').removeAttr('onchange').change(function(){
calculatePrices();
});
Now, in this calculatePrices()-function, alongside with some other logic, I included this to change the prices:
function calculatePrices()
{
var price = 0;
// some logic with custom options, not interesting for this question...
// Change the price according to the options:
$j('#select_20, #select_21').each(function(){
var selectId = this.id.replace('select_', '');
var options = opConfig.config[selectId][this.value];
if(options.type == 'fixed') {
price += options.priceValue;
} else {
// percentual change:
price += price * (options.priceValue/100);
}
});
// Use Magento Objects to set these prices:
optionsPrice.changePrice('bundle', price);
optionsPrice.reload();
}
