in general I find that the longer the bus journey, the more likely it is to be late!
there's no emigration checks when departing DUB - you just need to scan your boarding card to allowed airside
It's the Dublin Express service from Dublin Heuston station. I'll be arriving by train to Heuston so I hope Irish Trains are reliable

Otherwise... taxi.
