For 1.3 things have changed a little for us Chloromancers, opinion is divided on whether they are for the better with most feeling that they aren't and it isn't as fun as 1.2 but anyway I'll stop moaning
What it does mean is that generally it is felt that, where previously an almost even split between chloro and warlock + other 0 point soul was good, it is now pretty much required to have 51 chloro / 10 warlock / other soul with 5 points spare to do what you want with. I'd recommend Archon with 0 points added for the 'other' soul as you get a few buffs which don't take too much additional effort to keep track of and refresh (5 min durations).
These links aren't a bad place to start, i've got some other links at home but i'm working (honest) at the moment. Make sure you read into the comments section as some of the points are very valid.
I'll post my spec to show you where my extra 5 points went and some other info/sites I have bookmarked this evening. I'll also post my gear as most is AH / guild made or relatively easy to obtain (think i'm ~150 focus, ~750 sp, ~600 crit or something like that). Do the dailies in IPP for icewatch as they have some nice rings you can get early on (for dps or chloro in fact).
As always this is opinion etc so you'll find your own way and discover the bits you agree / disagree with
