I have experience working with servers and OSs and some networking but would like to become proficient in networking. Perhaps even take a certification test if I work hard enough at it and gain confidence. To that end I have mindmap and packet tracer installed. Are the labs in any particular order? Where do I find them?

You can try my examples in packet tracer if you want. If you want to try some labs on your own afterwards, you can try mine from GNS3Vault:
