mancow, if you want to be known for knowing your s*%* then go for system adminstrator/network adminstrator. MCSE cert. will get you mass knowledge and money.
the support specialist is rather weak. its customer telecom service. sitting at a computer walking people through your companies trubleshooting software. when your an admin, head and oversee a companies network, you have full control, and lots more versatility then a supprot specialist. and you get to take home more then there companies department managers
i'd startoff with A+ if you can get it in 6 motnhs or less while your going to school for MCSE. dont spend too much time on A+ as thats more so geared towards computer repair. as a system admin in a big company, you dont waste time fixing comps too often, you just buy new ones.
hope this helps, and good luck.
