Insulating under floor old home
 
I would greatly appreciate any advice for my situation.
Background:
* House built in 1904, located in Spokane, WA.
* Basement, two floors, and attic loft.
* Bottom floor is much cooler than second floor; in the winter when (basement) furnace makes bottom floor comfortable, 2nd floor is way too hot.
* Bottom floor (above basement) is made of only two layers of wood, each installed in a different direction. I would guess that some colder basement air may leak through the cracks in between the wood planks.
* Basement has thick old stone and concrete walls (part of foundation of home; there is no wood in basement walls). It has gas furnace, and does not have moisture problems.
* Basement ceiling is low (about 6'), and has wood joists 16" apart, about 6" deep.


Now, my questions:
1) If I put insulation up in the basement ceiling, would that possibly help warm up the rooms above? (If so, this could save on my heating bills and also make the temperature between 1st and 2nd floors in winter more even).
2) If I did put insulation, should I use faced or unfaced?
3) Would you suggest R19?
Thanks so much for any advice!!
