I have one year left on my PHD and am an assistant professor at a state college in Minnesota. I am also the lab coordinator. My salary is $58000 base. As for credit load, in the fall is our lesser time so I currently get 2 credits release for the lab and teach the other 9. Next fall this is changing to 4 credits because of the demand of faculty and the high use of simulation. In the spring I have 6 credits release for lab because of the high demand and 6 credits for teaching. Make sure to compare the cost of living in northern Mn to wherever you are at to see if the salary adequate for you.
