Only you knows the answer 3xban!

Do you have a pretty secure job? If it's the case, you don't need certs in the short term... You may be better going for a class that would help you and your employer (it will also be easier to get them to pay for the class...).

Do something you like, regardless of the cert. You must have seen by now how we, on the offensive side, praise the Offensive Security courses. We all know here that their certs are extremely valuable, but as far as I am concerned, the industry has yet to recognize them. Basicaly, being OSCP certified doesn't help you get through HR, but it helps you big time when it is time to do the real work...

So just focus on getting better at something you like. Your reputation and skills are far more valuable than certs.

And yeah, do CISSP when you have a chance... 

I self studied for CISSP. Here's what I did: http://www.ethicalhacker.net/component/option,com_smf/Itemid,54/topic,6675.msg35858/#msg35858

But you don't have to do it now. I was joking a bit in my previous post... 

Go for 8570-type certs especially the CISSP. The way I see it, the high-level certs are going to improve your re-hire chances if you lose your job (never say never) or want to move on. These will get you past HR. your current job experience will land you a job with the manager in your next interview... But you have to get past HR first. Since your current employer is willing to foot the bill, expand your HR fodder.

I don't see the need for a course for the CISSP. The material is so dry that it's just going to go in one ear and out the other after you get a few hours into it. It's best to take the slow-and-steady approach with a book and regular review. The actual exam is almost more about interpreting the questions correctly than it is about security, so maybe you could omit studying if you have stellar analysis skills

If you're looking for resume-building certs for a job change, browse job boards and see what's hot. GSEC is popular, but it's kind of generic, and there are a lot more people with those than any other GIAC cert. The GCIH seems to be the next most popular, and that one actually has some teeth to it. The 501/GECD material is also pretty solid. I've seen a majority of the books because I've written some exam questions for that one. Again though, check the job boards and see what the demand for that one is. I would suspect you'd find that one to be very useful for your day-to-day role, but relatively weak for career changes.

Regarding the mobile and virtualization courses, you can certainly pimp those on LinkedIn and your resume. Both of those are important technologies that pretty much everyone uses, and stating that you've had a SANS course on the subject is only going to help your cause. Although, I'd view those more along the lines of icing on the cake, as opposed to major attention-getters that help you get your foot in the door. I'd put those off until you've got resume fodder under your belt.
