Need help on new hydro air system

Hello, I'm a carpenter renovating my own home. I'm changing over from baseboard heat to hydro air system, keeping my existing oil burner. I was wondering if anyone could tell me how to figure out how many registers/sizes each room needs, how large ducts need to be, limits on length of the ducts, ect. I have general knowledge of working with ductwork, and I'm looking to do it right since its on my own home, but my budget doesnt have room to hire the man, so I'm fairly confident I cant accomplish the heating system, if I can get my hands on the info to do so.Obviously there is some formula to this, unfortunatly I dont have the knowledge of it though, so I appretiate any help/input from you HVAC guys out there. Oh one more thing, I was talked to a hvac guy we were using at work, and I gave him my square footage, and he said I need the 2.5 ton unit and to use a FirstCo. Could someone tell me how to figure that out too, being that we had 4 call backs from that job all dealing with the HVAC.hahahaha Thanks

You can use the charts from here to figure heating and cooling ductwork:

especially pages 8 or 9

or you can cut time with the estimate program:

I don't have a clue what type of heating your a pro at but, from what I see it isn't any I know of. A furnace manual to size duct and btu's, not any pro I know. The only way to properly size btu requirments is with a heat loss heat gain and size your duct work from that point. Enough said, there isn't a rule of thumb that is better than a guess. Get real.

Sorry, I didn't realize you were trying to sell yours

Here are the instructions on how to do it without a computer:

As I co-authored the H-22 used by the plumbing industry,
here is a free version that does that:
