I'll offer my advice as somebody who's already in the industry, though I'm on another continent, and not necessarily in the same career path as you might want (sysadmin).

I don't think anyone much cares about the Net+; at least I got mine in 2001 and so far nobody's cared. As for MCSE, it does hold some merit if you want to work in a Windows shop, e.g. "Sr. Malware Cleaner"© or "Certified Exchange Rebooter"™. Yeah, I'm a bit cynical, but I got out of Windows for a reason. Still, not all shops use Windows, but I haven't worked in a shop yet that didn't have at least a few Cisco routers. Plus, general network knowledge carries over, whereas MS knowledge is strictly proprietary (and quickly forgotten -- take my word for it!).

In your shoes, I'd spend my limited time and resources working towards certifications of more general technology, then gradually specialize as you get a better idea which direction you want your career to go.

All the best,
