Yes, you should read up to issue #20 of each of those series, I believe. (I'm pretty sure that was Johns' last issue).

You could continue from there - it's not a dramatic continuity leap between the old and new writers (not any more dramatic than any other writer-switch).

As far as I know, Threshold and that book about the Orange Lantern whose name I forget right now are not important... and also bad.
