I'm not sure about the stack temp you were told about. 300 degrees is pretty hot. The leisure line we test with in the shop certainly doesn't run that hot a chimney pipe. Even at full burn the pipe 3-4 feet from the stove (a diagonal section) is hot to the touch, but still touchable. Proper draft and barometric damper setup is essential to get the best efficiency, and thus proper stack temp.
The Coal-Trol Digital is able to hold the room temperature to within +/- 1 degree of your set temperature. The TS2 with 2 setpoints allows you to set two times and temperatures during the day, typically a day time setpoint and a night time setpoint. You have the option of upgrading to the TS1 which will offer energy star compliance (among other features). For a thermostat that means, in addition to holding a temperature to within +/- 1 degree, there are 4 weekday setpoints and 4 weekend setpoint that can be set. This allows for morning, day, evening, and night setpoints and thus more control of temperatures and fuel use during the day. Both thermostats offer improved fuel efficiency over traditional control methods: on/off thermostat systems, timer controls, and manual adjustment. This is especially the case when considered against the need for frequent adjustments of the timer and manual control methods in order to keep up with changing outdoor temperatures and other environmental factors.
