And, once you have the distance to the target determined to within a kilometre or so, do you actually lose much efficiency compared to a centimetre-exact distance?
Well, a kilometer or two can be quite a lot. Lasers work because they are highly focused, and I've heard of cutting lasers not doing anything useful if their focal length is minute fractions of a percentage off. Really, though, Luke Campbell is the better person to speak to actual tolerances.

That said (and linked), remember that as soon as you use any active sensor to ping the target, they know about you and should be assuming you're going to pull the trigger as soon as the signal gets back to you. This basically starts the Dodge Clock ticking and sets a minimum time limit - and consequently a maximum undodgeable range - on speed-of-light weapons. Nothing says the pilot isn't asleep at the wheel or his reflexes kind of suck. But those sorts of things are determined through surprise rolls and active defense rolls.

It also tells you that the most weapons will attempt to extend their range to that point, but the number that try to exceed it will drop off due to reduced efficacy. I'd expect the typical range of space-based weapons to be something like a skewed Guassian distribution with the mean around the maximum undodgeable range and weighted toward the undodgeable side, since that's the more effective side of things. Of course, super-long-range lasers are still plenty effective against unsuspecting, unpowered, or particularly unmaneuverable craft.

I'm not really surprised. It looked pretty high, but I wasn't vetting anything when I grabbed the number, and we all know how reliable the internet is. Either way, even if it is that high, somehow, it wouldn't break my suspension of disbelief for futuristic computers to do this effectively instantly.

That rule doesn't add any rolls to the attack resolution sequence. It just limits defenses in specific ways for certain weapons.
