Re. gold - there is no Islamic limit on mahr, other than opinions - some of which are grounded on hikmah - others which don't take into account the financial weight of the parties involved.
More gold means more zakah :) so see it as an opportunity for a high standing order into Allah's account - if you have it - and if you don't later on - the bride can easily weigh the amount out of the total and still pay.
Try to make sure her priority is aakhirah and you will be happy inshaAllah.
