No, not necessarily "attractive" items-- rather, he wants some items that look like they could be wielded by someone fighting for right, for truth, and for justice. Since Blackwing Lair in vanilla WoW, most of the higher level items look scary-- they're black and spiky, with dark magics streaming around them. Not exactly the kind of thing that a true worshipper of the Light would want to be seen with. I get what Silrad's saying-- he's not a hardcore RPer, but he wants to look like a good guy, and it's tough to do that when your shield has skulls all over it.
Unfortunately, considering who we'll probably be going after in Northrend, odds are that we're in for more gothic, frosty death armor. But there is good news-- Blizzard has already said that even though we're headed into a place where they have something called the Frozen Throne, it's not going to be all ice and snow. There will be at least one Dwarven instance, and you know those Dwarves are interested in: your regular old shiny, gleaming, good-guy steel.
True, if you're playing a class called a "Death Knight," your armor can't really be pink and frilly-- it's got to have some skulls, black plating, and blue magic on it. But hopefully the artists on Wrath will find a few places to put some good old "knight in shining armor" armor out there for us.
