I like Gosick, so I'd recommend checking that one out at least. The main character Victoria (sp?) is amusing to watch and is probably my favorite part of the show.
Infinite Stratos... uh, I don't really recommend it? It's not bad... it's not just not really that great. The plot has been done again and again: male student who is incredibly special attracts lots of women, add in fan service and a few robots, and you got yourself a show. I guess this show could be labeled as action/mecha as well, but it's not really that interesting when they do add it in.
