The rule of thumb is 1 ton for about 1000 SqFt. I will say at least a 1.5 Ton unit, especially if you are planning to add more space to your house. I am not sure what kind of heating you are using but there is split systems with heat pumps and other options to accomodate your heating too. Call your York agents, they will help you out.

It's doubtful there is a standard. They come in a variety of sizes, shapes and materials. See, for instance, the ref. below.

There are plumbing fittings down to 1/8" that are fairly common.  I am not aware of things like sanitary tees, but fittings like 90s, tees, 45s, etc. are available.  They might even be in your local hardware store.  If the 1/8" size isn't available they also make 1/4".

Try contacting some of the major manufacturers. Maybe they can point you in the right direction.

In this answer I am going to refer you to an online calculator. The power company is simply trying to get an idea of your power requirements to establish a transformer and feeder size for your home. I will also tell you in this article va is the same as wattage. You will need to know the square footage of the home , whether you have gas or electric range and dryer , small appliance and laundry circuits are a given in all homes. 2-small appliance and 1 laundry . Also needed air conditioning load if applicable , or heat pump if applicable etc. If you have a copy of the National Electrical code available to you there is a sample house load section for single family dwellings that will  be helpful. But I truly feel for your purposes the following site will give you everything with a simple fill in the blanks format. If you have any questions Ill be happy to help. Ok heres the url for the calculator.  http://www.electricalknowledge.com/SFDLoadCalc.asp
