Three-Wire (Heater) to Home Wiring

I would seriously suggest leaving wiring 240 volt power to an Electrician.

A mistake here could be "life-changing".

Three-Wire (Heater) to Home Wiring

Product in question is 153.329563, 55 Gallon Power Miser series 9 Electric.

The water heater is (nicely) wired for timer or off-peak metering, which leaves a total of, technically, four connections:

Blue Wire, Yellow Wire, Black Wire and Green Grounding screw.

From what I can tell, when wiring to a three-conductor home line (Line 1, Line 2, Neutral/Ground) you are instructed to pair the BLUE and BLACK wires, and connect them to Line 2. Then, you connect the Yellow wire to Line 1. Of course, you then ground the third lead of the home line to the green grounding screw found in the water heater junction box.

Is this correct?

I have 7 people in my house, and a 50 gallon works fine :)

Sears does carry 75 gallon water heaters, though it's excessive for the quantity of use you're likely planning, unless you need everyone to bathe at the same time. I'm not sure anything short of 100+ gallons would be able to accommodate that kind of demand.

There are other means of increasing hot water production, though. For instance, strategic use of certain appliances. If you set your timer to run the dishwasher a few hours before people start showering, there will be more, hotter water. Same goes for running hot laundry. If we run our dishwasher before we take showers, the water is like lava coming out of the pipes.

The biggest electric (residential) water heater I have seen is 120 gallons,made by Rheem. You would have to look in your local phone book for a dealer,they dont sell too often so you might have to order it.Much more likely you could get a 80 gallon off the shelf.Ask your plumber,I am sure he will know where he can get one.Get on the phone first thing in the AM because the supply houses will be closed on the weekend.
