I put on the Mishimoto dual elec fan setup last summer. The previous winter, after putting in the big Mishi alum. radiator, my car would never warm up (I put in a 192 degree t-stat and new water pump at the same time.), so my wife refused to ride in the car with me with no heat. I mean the temp wouldn't rise above the "L" in "NORMAL." So taking a cue from my sportbike, in which the elec fan barely ever comes on, and never comes on while the bike is moving, I figured I'd put an e-fan on my car and get some heat up in here. Since I put it on last summer, I hardly ever have the e-fan on unless I'm in bumper-to-bumper traffic, and as a bonus it feels like an extra 5-10 horsepower. The engine revs real quick now, you'd be surprised how heavy the stock fan/clutch setup is. To answer your original question, if you are going to have an engine-operated fan, you should have a shroud. Especially if you are frequently under the hood of your car. Can you say, "Chopped off fingers"? The factory shroud/coolant tank setup should work in your car, kind of depends on the radiator because the factory shroud bolts to the actual radiator, and the coolant tank screws to the shroud. You would be more environmentally-friendly with a coolant overflow tank, as the car would be fine without it (cars didn't have them for 60 years until the early 1970's), because when your car warms up now, it just spills coolant on the ground. The overflow tank allows the coolant to expand into the tank when it's hot, and then pull coolant back into the radiator when it cools down.
