There's Groundwork of Gurren-Lagann #1 and #2.
The Yoko AND Nia Photobooks. I'm kicking myself in the arse for NOT getting them at SDCC (no tax).
The Drill/Mook books.
...and a few more that I know Kinokuniya has in stock.
Leeron's definitely good. Yoko too.
Kittan was awesome. The sisters were just fine.
Simon is still growing into it but getting better.
Kamina showed promise with episode three.
It by all means isn't "crap".
