So, is the first thing i need to do:
1) buy a new thermostat? (I have had the car 6 months, have not replaced it in that time, and don't know when it was done before i got it.)

The code is actually an indicator that the engine stays too cold for too long when the vehicle is moving ... NOT that isnt getting hot enough.
A stuck open thermostat is the most likely culprit ... but the CTS and the connector could also be the issue.
This might help ...
1995 FSM ...
17* ... Engine is Cold Too Long.
Engine coolant temperature remains below normal operating temperatures during vehicle travel (thermostat).
1997 FSM ...
17* Engine Is Cold Too Long.
Engine did not reach operating temperature within acceptable limits.
17** P0125 Closed Loop Temp Not Reached.
Engine does not reach 20°F within 5 minutes with a vehicle speed signal.
20*f is -6*c
160* is listed as a warmed temp in the FSM
First thing to do is verify the running temp .... Whats indicated on the gauge ?
How long does it take to warm up to at least 160* ?
Has the indicated temp changed significantly in the 6mnths you've owned the vehicle ?
Clearing the code and seeing whether the code 17 comes back might also be worthwhile .....
Testing the thermostat as tazwegion suggested is also a good move .... but if you remove the old one - that you dont know the history of ... you may as well replace it.

You'll probably find a 190* or 192* is more commonly available .... 195* is NOT a nescessity ... as indicated by the listing of a 180* as a chrysler spare parts option.

Yes ... Very generic .... Its a common as muck thermostat used in a bunch of vehicle brands and models for years .... Theres nothing special about it ....
Dayco DT14 series or Tridon TT1 & TT2000 series .... and theres other brands.
