Answer 1

Instead of wasting money on the oversized copper, especially the 1", you would be better off with 1/2" with separate runs to the two baths from the entry and hot water heater and with reductions from that.  Toilets and basins do NOT have 1/2" connections - most of the hoses are 3/8" ID or 1/4" ID.  The tub and shower have 1/2" feeds but showers these days are so restricted as to require much less water flow.

Answer 2

Scrap the copper and go with PEX.  This is plastic water lines that connect with compression fittings.  It's much easier to work with and the cost is a fraction compared to copper.  Another pro is installation is a fraction of the time from copper.  It's also just as durable and in some cases better than copper.  

Have you seen the price of copper pipe lately?  It's outrageous.  I wouldn't pay that much if I didn't have to.

Answer 3

follow the size you took out.
