OP: Unless you expect to spend a LOT of time a the track and if noise, vibration and harshness issues mean a lot to you, stick with all stock mounts, except possibly the rear motor mount. These cars tend to have a problem with the 2-3 gear shift under full throttle. Upgrading the rear motor mount is a huge help in that regard, but at the price of some vibration at idle, especially when the air conditioner is on, and some gritty harshness under some operating conditions.
I've tracked my car a good bit and got over 40,000 miles on the stock mounts, but with frequent missed 2-3 shifts under hard driving. I finally replaced the rear mount and have just about eliminated those missed shifts up into third. Even with the softest street mount from SURE, there is that vibration and grittiness.
BTW: If you ever go with an aftermarket tune, such as AP or Hypertech, both tunes offer a way to increase idle rpm. By raising idle speed by 200 rpm, almost all of the vibrations associated with the mount upgrage go away.
