A few links wot I recommend:
Josh of Eye For An Eye has posted an excellent guide to playing Retribution in Wrath – for those of you planning on picking up PvE Ret as your second spec, this is pretty much invaluable, especially if your last experience with Ret was back before Molten Core like mine was.
As a counterpart, Ferraro’s blog Paladin Schmaladin provides a good analysis of talents for Ret paladins; if you’re trying to L2Ret, this is a good summary of the decisions you should be making – and the reasons why.
On a non-Paladin note, I recently stumbled across Artisan Level, a general WoW and Guild Leading blog that I’m really enjoying; great writing and relevant – if fairly non-specific – content. You can find it at oriniwen.wordpress.com.
For the longest time, I thought I hated world PvP, and the idea of a PvP zone in Northrend filled me with ‘meh’. But on a whim I tried a couple of games of Lake Wintergrasp and found I really, really enjoyed it! If you’re interested in checking it out, Mooonfire! has written an excellent guide: “Ten Things I Think You Should Know About Wintergrasp”. It’s definitely worth a read; some Wintergrasp mechanics aren’t at all clear when you first try it out, and a guide like this is a great help.
And one last link useful for anyone who’s likely to be tanking – or off-tanking. Honor of Honor’s Code has written a useful guide to tanking caps in WotLK – uncrittability, the block cap, the hit cap and the Expertise cap. Dedicated tankadins probably know all this, but it’s a handy reference for those of us who are, at best, part-time tanks looking to work on our offspec gearing.
