Definitely go with bullet points. Whittle down the wordiness in the LT Skills, Employment History, and Personal Qualities sections (this last area could likely be included in a cover letter if requested, rather than in the CV itself, although that's at your discretion).
Also, I truly doubt it's necessary to include high school course work and the actual letter grades for individual curriculum areas. Simply including a line stating that you received your high school diploma should likely be enough.
All in all, I'd say you could likely compress the whole document to one page while still including roughly the same amount of pertinent information.
Edit: Although the above advice should be taken with a grain of salt, depending upon for what circumstances you're planning on using the CV. I know that in my field, your education and employment histories generally receive a page or two at most, including doctorate-level studies and professional accreditation. Everything else is reserved for talks, presentations, and publications.
