go for the CCNA now and then go after the CCSP\CCIE Security. This will always be a sought after and rewarding skill.... especially with the federal government.
While certs like these will do you good on paper, if your desire is for a management level positon then I would go ahead and start moving towards an MBA.
Cisco Certifications are a "nice to have" but if you aren't going to use routers everyday and deal with straight infrastructure based networking, which it doesn't sound like, you really have no need for a cert past a CCNA. The difficulty of the CCNA is increasing with the next test change, and the CCNP (which is a perquisite for the CCIE) is a compilation of tests both written and LAB based. Then after you have passed the CCNP you can then start studying for the CCIE... don't even get me started on the test sequence for this mamma jamma. I would suspect that if you really aggressively went after the CCIE it would be a couple years until fruition and an MBA would be at max, taking a reasonable course load, would be a 2 year ordeal and much more useful if you are seeking promotion.
