Hard to get into gear before its warmed up - 2005 Ford Focus

the gears would heat up and possibly bind some since clearances are so tight so it might cause that try filling it

The car pulls suddenly hard in forward or reverse direction at the moment you change gears.

check the clutch operation especially the m/cylinder for failure. The fluid and the master cyl. is probably not disengaging the clutch enough. the rears will not necessarily grate as the synchros are working overtime to spin the gears for alignment because the clutch shaft is still moving under power from the engine.

It sounds to me like the transmission is starting to fail. As the clutches inside the transmission wear the clutch pack gains additional clearance. Your pressures in the transmission will be higher with cold oil so it has a tendency to build a bit of extra pressure, but it's also slower in flowing through the transmission. This results in a harder hitting first gear. As the transmission warms up, it will reduce the viscosity of the oil and work fine. Cold weather kills automatic transmissions. Let it warm up before driving it or it won't last long. It will require an overhaul soon.
