good luck with the job hunt! I'm not going to get any certifications, but then again, I'm not a tech professional.
for resume/CVs? if you do a quick google search there are literally thousands of guides out there... I only have hard copy guides I got at school, unfortunately, they're all aimed at business students, and not certified professionals...
While it may seem a bit unnerving, almost every employment centre can help you out with mock-interviews, interview tips, and other guidance along those lines.
Sorry I can't offer more concrete help, but at least it's a start in the right direction!
