Yes nice thick tubes etc will certainly help to dampen vibrations and without a doubt, you need to look at the gantry weight and screw sizes you'll be using to help with motor selection, etc. Mass in the gantry certainly helps here as well but this does come at a high cost with motors etc and isn't always needed so it's worth taking the time to work out the weight you'll be moving.
