Once you've plotted 3 points 3:15 apart and they're in a reasonably straight line and the same distance apart, you've got the course and speed. If they aren't in a straight enough line or aren't the same distance apart, keep plotting until you've got three that are, as long as the target itself is not trying to evade you but moving in a straight line. If it's already evading, you have other problems.
When I'm plotting my 3 points, I'm often running at ahead full on the surface using the WO's nearest visual contact reports. (Edit to add: I've got map contacts turned off.)
If you're talking about using hydrophone bearings, it's easier to do it while stationary, but it can be done while moving... generally.

If you are confused then I have no hope!
I am in agreement with you, however. I can't quite figure out how me moving will matter when I am trying to determine a targets speed and its movement track. If i use the 3:15 rule, than me moving should have no bearing on whether I can determine its speed.
The same logic should also follow when trying to determine its track. As long as I have marks of the target over time, I should be able to plot it track no matter my movment direction or speed, correct? What does it matter if I am moving if I am plotting points on a map of the target?
Yet there is a whole tutorial on moving while plotting done by Wazoo here:
