For body mounts, IMHO< I would keep the oem style units. Urethane while great for stiffening things up, in a street vehicle, it takes that unibody and increases impact forces in areas that over time (and dependent on road conditions) will be destructive (such as tearing body panels at connection points, etc.) and it's not exactly a "nice ride"...... ona longer trip, you will feel it yourself from a standpoint that it is physically tiring as compared to the less less harshness of the oem style bushings. As far as sway bar bushings, etc., sure, go for it.... it will be a bit of improved handing and you will feel the increased stability but the general NVH aspects will be comfortable
