Nooo!
That's a common misconception. Distance to target being irrelevant is
only when the Gyro angle is zero or close to it. If you set yourself up being angled 45 degrees across the track (with AOB set appropriately for the bearing) while still aiming with 0 gyro angle, then it is also irrelevant. 90 degrees across the track only gets you his best broadside, and hence best margin of error for speed estimates. Distance is only irrelevant if the torpedoes do not need to turn. The minimum torpedo arming distance taken aside, that is.

Nope only AOB, and thus course after considering the bearing in relation to your own course. Speed and range need for you to be displacing after the 3rd and look from a different vantage point to see where it crosses a forward projected semi-4th bearing. For the 3-bearing method, make and play around with
(link)this. It has been incorporated in one or more of Makman's GUI mods.
But there are also other 4-bearing and even 5 bearing methods that allow you to be moving the whole time, described in the SH4 and SH5 section. Just do a search for hydrophone and names like Nefelodam, Kuikeg, Stoain and Makman (iirc the proper spelling of their names). You'll find them.
I too consider this just a method to get close enough, and get an estimate on their speed and distance. But it has to end in visual contact before torpedoes start swimming. Can't have friendly-fire incidents, you know.
