I worked for MSFT for 6 years and, ironically, they never asked to see my MCP transcript in the interviews or at any other time (no, most MSFT employees can't look it up, either). Didn't stop me from meeting everyone from BillG on down. I did have MCSE+I, MCDBA, and MCT but the only people who ever asked about it were other geeks who wanted to tell me how many more tests and certs they had than I did.
Get the certs if you want, but spend as much or more time talking to the business people, especially in sales and accounting, and solving their problems. Do a seminar for them on security or "tips and tricks" with the latest software, mobile device, whatever. Volunteer to be the "IT liason" for one of their projects so you can be part of developing the solution. Every cool job I've had has been because someone I helped in this manner moved up and then put in a good word for me, too.
