When writing your CV and you put down your skills what should you include and leave off?

For example I have got some Java experience, I got one of the highest marks in the assignment, and understood a lot of it, however I wouldn't say I was good enough to be a professional Java programmer.

The same applies to C/C++, I have produced windows applications but I am not expert.

The area I am becoming quite expert in (developing accessable CMS systems for websites) there seems to be hardly accesseble jobs, they are all too high end requirng commerical experience and I don't have much of that.

I've realised due to personal issues like moving out I need to get a job for a year at least before starting my own business.
