Answer 1

Using the alternative calculation method in the national electrical code, you would need a minimum service rated at 95 amps. With taking in to account the method utilizes 125% of the largest load ( your oven) you can get by with 100 amp at a minimum. If you plan to add any future electrical items, hot tub etc, plan on 150 or a 200 amp panel and service would not be out of the question.

Today for you new home a 200 amp is more the norm than not.

Answer 2

Most older homes and early subdivision homes were equipped with 100 amp service because there were few systems other than water heater, electric lights , clothes washer and furnace motor using power. Clothes were dried outside on a clothes line.Then came the central a/c,electric range,toaster oven, dishwasher and dryer,disposall, bathroom vent fans, attic vent fans, basement workshops, garage door openers, mixers, blenders, knife sharpeners, can openers and gadgets. The modern house has a minimum service of 200amps and several newer homes have 300 amps available most with circuit breakers.

Answer 3

You can't install anything less than a 100 amp distribution panel so I would go that route 100 amps will be fine. If you plan on adding things in the future go 150. any higher than that and I would need to know the distance you re from the service.. (pole) but for what you describe without knowing I would guess 3BR 2 bath, 100 will be fine..
