Replacing Evaporator - What else?

[Ifixtheinternet]

I need to replace my leaking evaporator, along with a few other components on the AC system, including the compressor.

Considering the large job, the whole dash and hvac box have to come out, coolant drained, ETC, I want to replace everything that makes sense while I'm in there. 

should I preemptively replace the 11yo heater core even though it's not leaking?

should I replace the air mode door actuator?

Heard this was a common failure on some of these cars but not sure about this one.

Anything Else related to the HVAC box I should look at acquiring while I have everything apart?

I'd probably do the filter drier and expansion valve too.
