Digging up my copy of the Voyager 2 Jupiter encounter imaging report (Smith et al. 1979, Science ), I see that Voyager's best resolution on Europa (from Voyager 2) was 2 km/pixel. So Juno could easily do better.

The best resolution images of Europa by Voyager 2 were at around 1.33 km/pixel so the resolution quoted by Scott Bolton would be in that ballpark.

As Mike says there are large gaps in high resolution coverage of Europa, so the close imaging may indeed improve mapping in some areas. For Io even fairly low resolution imaging (though I still mean an order of magnitude better that existing Juno images) would show surface changes, and we know they are frequent and substantial. Certainly good science to come from that. It doesn't look like there are useful opportunities for small satellite imaging.

With regard to improving resolution, keep in mind that the satellite encounters can't be done for the convenience of imaging and the geometry is highly constrained by the spacecraft spin and spin attitude, so anything we get in that regard will be largely serendipitous.

And of course the extended mission is subject to approval and funding.
