Also, when taking off normally in auto, when the car shifts into second at about 2,000 RPM, it feels like there's a drop in torque for a couple seconds, and that's when the problem starts.
Sometimes when I come to a complete stop, the RPMs will dip below 500 then jump up to about 950, although I'm not 100% sure the two are connected.

In regards to the rpm drop upon stopping, was your AC running? AC compressor is a parasitic draw on engine power. It will cause that rpm dip. It's normal if that's the case.
