We are trying to start milkweed in our germinator. How hot to set thermometer? How long to emerge, and how wet? Anything else we can do to improve germination?

Generally it is quite easy to direct sow the seeds into the garden.
In the Fall you can scatter the seeds in the planting area and the cold winter will provide the seed stratification needed for the seeds to germinate.
If you purchased seeds from a vender they should have had information provided if they were prechilled.
If starting indoors (which you have done) you should plan to start them approx 4 to 8 weeks prior to last frost date.
You can start in trays of potting mix or even larger pots. Plant the seeds about 1/2" deep with 1/4" of soil on top. Keep the soil moist.
Germination should be in 7 to 10 days and temperatures should be at 75 degrees F.
Make sure the seedlings to not get wet by watering from below as they can die off from dampening off quite easily.
