We have heated with L.P. gas and have for years and cooked with it for 45 Yr.s. It is only smelly if it leaks. They put an odorant in it to let you know it is leaking.
We have had a wood buring stove to make living area more comfortable for the last 25 yr.s and we keep a pot of water on top, and I think it helps. Dry wood is a must.
