Have I got Rel Canonical or not?

[borderbound]

I have 180 warnings of  rel=canonical.

The exact wording says this:

Using rel=canonical suggests to search engines which URL should be seen as canonical.

First - I don't know what that means - is that a good thing of bad thing?

Second - Because of the above question, Im not sure if I have it or should have or it do have it but shouldn't.

Which should I have? What should it look like? How do I fix it?

Also,

I have notices that say 'issue: 301 redirect' and a line about what a 301 redirect is.

Again, do I have it, or not have it, should I have it? Do I have it but shouldn't?
