I plan to start taking a coarse: Computer Networking Technican:

http://www.siast.sk.ca/programs_courses_descriptions/CNTCERT.shtml

Is this coarse absolutely useless?

A also plan to get security +, A+, N+, and defiantly CCNA.

So would the Siast Computer Networking Technician be a good start?

I am not very familiar with SIAST, but they seem to touch on all the courses that can give you work in computer repair, networking, help desk, and tutoring others.

Ten years ago, I independently took MCP Windows NT, A+, Cisco 1 & 2, Windows Server, Microsoft Office, Visual Basic, and Java course work from a technician's school and from a junior college. They were all helpful for me as a technician, consultant, network engineer.

A+ and their related certifications like Network+ and Security+ are good certifications. CCNA and Microsoft Certified Professional also open doors. Back in the pre-dot.bomb days, any of those certifications paid considerably better than BA and BS degrees in ANY field (salary survey, Visual Basic Magazine). These days, while not "better" than a degree, it's still a good salary.
