Ah, sorta. While you definitely got the right idea, just a few things might be optimised.
First, in terms of gear, you seem to be doing fine. There's a good site,
Warlock-Loot, that tells you the good warlock drops from zones and dungeons. Highly useful. Also, Make sure you do the ring of blood event, some really nice stuff from that.
Worst thing I can see is the lack of a second profession. You might just be the type of person that hates 'em, but they can definietely come in useful.
As for talents I would go for something like
this.
The only changes are getting rid of Imp.Hs, Imp.Health Funnel and Suppression (which you will need later for early raiding, useless for leveling though) and add in points to Nightfall, Grim Reach, Imp. Howl of terror and destruction. That just optimises the build. You are drain tanking right?
Now some might disagree that suppresion is useless for leveling, seeing as it does hit cap you against equal level mobs, but the difference is tiny so meh..just like the difference between your build and the one up there. Personally, I wouldn't bother re-speccing till 70 to save money.
Edit: Yep, wrong url.
