One part says Paladin(Divine Defender) and then later Paladin(Sacred Shield). I would consider taking a third paladin level with Holy Tactician. Ideally with Torag's Defensive Strategist trait.
This will let you spread lookout to everyone in 30' for sweet no-surprise love. And if you pick up a second teamwork feat, you can swap to that after the fight starts as a swift action. Outflank and Escape Route are both good options.
I LOVE the Holy Tactician. I've got a Brawler 1/Holy Tactician + Holy Guide 2. Next level, I'll be able to learn a new teamwork feat as a move action and give it to everyone as a swift action. At level 6, I'll be able to give everyone two teamwork feats at the same time, once per day.
It takes a lot of planning and feat investment, but I'm hoping it pays off well.
