It did seem to have about the correct percentage of questions for each domain. As far as preparation goes, I have about 6 years experience as a network admin and I used CBT Nuggets, the Security+ StudyGuide Third Edition from Sybex (which came out around the first of May this year) and a couple practice exams from PrepLogic and the one that was included with the study guide. And Techexams of course! I spent about 10 days preparing for the test. For me a big part of the test was more common sense; a lot of the questions had only one obvious answer. There were a few questions that were not worded well. For me my experience was probably the best asset I had going into the test.
