You'll have to go with your gut on some of those. They're certainly not as recognized as CISSP, pro/expert Cisco, or GIAC certs in general, but they could certainly carry some weight with the appropriate crowd. Does your company do a lot with 802.11? You're not going to be covering cellular in CWNA or CWSP. Unless you have an immediate need for them, or expect to move into a new position where they would greatly benefit you, I wouldn't bother.
Also, CWSP was totally a let down on the offensive side (nothing against CWNP; my expectations were way off). It's gone through a revision since I took it (which does look somewhat better), but you spend a lot more time dealing with the various EAP flavors than anything related to attacks. It's important material if you're tasked with implementing secure wireless solutions, but it was too bland from my perspective. I'd recommend OSWP and/or GAWN as alternatives.
We do work with 802.11. As a VAR we resell some motorolla and aerohive gear so it isn't like the knowledge would be completely wasted. I don't work with 802.11 daily (or weekly). Also I thought CWNA covered more than 802.11. Doesn't it cover basic wireless theory for all wireless networks?
I guess I see your point. GCIA would be so sexy and I have drooled over it for almost a year now. I know a few guys who have taken it and even a few who have challenged (at one point weren't you going to do it?

) I'm just a little gunshy of a $900 bullet.
