An honours degree will be better than no honours at all. Esp in the public sector (govt). Think that you should go for it. As a graduate you are expected to handle more responsibilities like running an IT project and so on. You may do some coding but if you do not intend to specialise in one area, then most likely you will find most of your time spent on gathering requirements and fixing bugs.
The extra certs (MCSE, Cisco) in themselves are not useful if you have zero experience.
Guess you have to weigh the opportunity cost of both choices.
Btw, job market now is not too hot now...
