The discussion has evolved from the original question, I think, but I passed the exam 12 or 13 years ago. I didn't find it easy, but it wasn't especially hard either. However, I was familiar with around 70% of the material already due to my job. The most painful part for me was the memorization of certain things. There was a list of ports I needed to know and I only used some of them regularly, there were a number of different attacks that I needed to be able to label correctly, there were different ciphers and encryption protocols that I needed to remember specific characteristics of, etc. In addition to the extensive note taking done while reading the guide, I made several lists and memorized them, and as an aid, did a brain dump onto the scratch board before I started the timer on the day of exam.
My main study material was the official CompTIA study guide, instructor's edition. (It was either the same price as the student version, or $10 more, and it was worth it to have the correct answers to the exercises). I don't think it's still available from their site. The exam becomes much more difficult if you don't have the background going into it to understand the concepts that are being taught/tested. Several co-workers have been studying for it for a while and just listening in to some of the study sessions you can tell that often they're having difficulty understanding what the question is asking. They're lacking some foundational knowledge that would make it much easier for them. Still, it's definitely doable with self-study. Other co-workers have done so successfully. The current version of the exam is old enough now that the major publishers should have comprehensive study materials.
I don't have a specific recommendation for practice exams, but practice exams from a reputable publisher can be very helpful. They can help you evaluate your level of readiness, help identify your weak areas, help your understanding of the material (because a good exam should not just give the correct answer, but an explanation of WHY it's the correct answer and/or why the other answers are incorrect) and help you to be more comfortable when you go for the actual exam. Once you have the certification, you'll need to maintain it, either by earning CEUs or by paying CompTIA another $200 for "online training" every three years. The payoff to CompTIA is the best use of time/money for me, but it's up to you. It's possible to maintain it by investing your time and not spending money out of pocket.
If you're going to take the exam, I think you need to commit to putting a significant amount of time into studying over a relatively short calendar period. I'd suggest an hour or more each night if you can possibly do that. Figure on 4-8 weeks for self-study, depending on your knowledge level going in and how much time you can put into it daily. If you have to stretch this out for 6 months or more, I think the chances of success go down. If you're not using the knowledge on a regular basis, you're going to forget it again.
As mentioned, it's been 12-13 years since I took my exam and it's been revised several times since then. They've added some performance-based questions where you have to interact with the exam software and complete some task or accomplish some goal. I don't have any hints for those scenarios, except to take advantage of any opportunities you get to practice these types of questions. You don't want your exam to be the first time you've attempted that sort of question.
Good luck and realize that if you're going into infosec, that will only be the first of several exams you can expect to take along the way.
