Joseph,power flushing is used to remove any rust or sediment that may be in the system/ radiators. before you go through that expense i would replace the air valves on the radiators: http://www.homedepot.com/p/6-1-8-in-IPS-Angled-Ste...these can sometimes clog and effect how the radiator heats up. the steam fills the radiator and sometimes will trap air in there, if the radiator cannot release that air the steam cannot fill the radiator to give you the heat, that's what these valves do, they let that air escape.

I want to remove wall to wall carpeting and finish hardwood.

This entails sufficiently sanding/scuffing ALL the surfaces being painted... a very tedious, time-consuming process on raised-panel doors.Or, you could remove the doors and drawers, take them to a furniture refinisher or cabinet shop, and have them prepped or stripped (a lot of these shops have strip tanks which makes the process easy).

you can get a few contractors in to see what type of walls you want to remove and a rough estimate but you will need plans from a structural engineer.

In a worst case, it could have negative value, because most buyers will see it as something that must be removed.
