I've got the Gunnar glasses and I love them. There are many independent reviews out there (just do a google search) and they all say that the glasses are worth the buy--IF you already have issues with headaches/burney eyes/dryness etc. If your eyes are perfectly fine, not worth the money. If you have issues, yes worth the money.
As for the Razer Anansi & the Nostromo, I'm using both right now for WoW raiding (both purchased as refurbs through Woot, in fact). The keyboard is pretty sweet. I really like the feel of it; I know it's not mechanical, but it feels like one, all nice and clicky. High quality. The Nostromo takes some time to get used to. In the end, I had to draw a map to show which numbers on the cast bar were assigned to which key. The learning curve is bigger than with, say, a Steelseries MercStealth keyboard, but the software support is so much better from Razer. I've only tried out one macro on the Nostromo, but it works just fine.
Finally, the Razer synapse 2.0 software is niiiiiiiiice. It's really easy to use and intuitive, and you don't need any manuals to figure it out and get going right away. Lovely. I recommend all three.
