I'm about to replace carpet and want to fix some squeaky areas at the

Since I can tear off the carpet to do this, I don't need to use those
special snap off screws for carpet, right?

Can I just use a generic wood screw (countersunk flat head)?
Is 2 inch about right length?
I put about 5 lbs of deck screws in my livingroom and diningroom
floor before I installed the hardwood, and another couple of lbs in
the hallway and stairway before replacing the carpet. IIRC I used 2
inchers -same screws used to put down 5/4 decking.
