If you have never used BIN before, I suggest opening ALL of your windows, and wearing a mask. The smell is extremely strong.
In my opinion, Zinsser Cover Stain (oil based) works as good as BIN, with less odor,and its cheaper. The dry time is longer though, at 4 hours or so.
Ditto on opening windows with either product. BIN is a shellac based product with an alcohol base.
Both are excellent but BIN would be superior choice to cover stain if you are trying to seal in whatever is causing odors. If it is pet stains, you really should postpone your carpet install and treat with a bacteria/enzyme product like Anti-Icky Poo (crazy name but of all of them I have tried it works well) before sealing the floor.
I am sure you are anxious to move ahead with new carpeting but your best shot at resolving the issues you face is with the bare subfloor exposed. It will be more challenging to impossible to deal with if you do not remedy the situation and end up putting new padding and carpeting over it.
