I completely agree with what Richard said.
Since you asked for "general cv advice", I thought I'd list some things that people often put on CV's that I think shouldn't go there. Some people might disagree with things here, but what's the internet for if not making controversial statements?
The places where your papers are submitted.
Undergraduate honors other than various flavors of "cum laude" (ie membership in Phi Beta Kappa). The only exceptions I would make here are Putnam fellows or the Morgan prize for undergraduate research.
Membership in professional societies like AMS/MAA/AWM unless you have some kind of official role in them. For instance, it would be appropriate to list it if you were president of your local chapter of the AWM or if you served on a committee for the AMS (I know of at least one postdoc who has done so).
Too many papers "in preparation". It's ok to have a couple of papers listed as "in preparation" if you actually have some kind of draft written. However, I have seen cv's in which the author has more papers in preparation than written/accepted. This definitely looks like padding.
For a graduate student, it's probably ok to list talks in the graduate student seminar or your thesis defense. However, once you have left graduate school these should probably disappear.
