Sorry I let this one slip for so long; I was, fittingly enough, on vacation. Now I'm back and going through pretty much exactly this, so I have a few things to say.
I guess my main advice is to wade through everything in newest-to-oldest order, which might be counter-intuitive. The disadvantage is that you don't really know what you're getting into for a while. But the upside is that you don't spend much time on stuff which has already been resolved or taken a drastic turn, which is enough of an advantage for me to make it worthwhile.
Cheers,
Roger
