Hi FF,
The official website that you should be looking at to obtain correction information about the requirements is http://www.immi.gov.au This is Australian Immigration's official website. Any other websites that you may view are companies that are offering a service to assist in the processing of specific visas. However, the information on those company websites may not be update to date since the Australian Immigration at anytime can make changes policies,etc.
I've pasted some direct url address in the website that has information that you need to review about the skilled migration visa. I believe you may have briefly reviewed this already? From personal experience since I have already been through the process of applying and later being granted the PR visa, the information you see in this website is what you need to follow.

There are a couple of things you need to check before you apply for the skilled migrant visa. I'm assuming you are interested in the Skilled Independent Visa 175? For this visa, you do not have to have a company sponsor you to apply for this. You are applying yourself. If you are granted this visa, you will get a permanent resident visa which is valid for 5 years. After that, if you meet the residency requirements, you can apply for Australian citizenship if you choose. If not, you must apply for a return visa if you want to travel outside of Australia. All this information is in the website for you to review.
One thing to note is that once you submit for any visa application, there is no refund if you change your mind. Only in very special circumstances will the Australian Immigration will grant a refund. I don't know what these circumstances are. But just make sure if you do change your mind that you are prepared to not get a refund. For this reason, it's best that in your initial research, you do meet the 120 points test mark and that your skills qualifications have been assessed by the Assessing Authority of your specific occupation.
If you fall below 120 points and above 100 points, you will be put in a waiting pool for about 2 years until you can increase the points to 120 points. If you fall below 100 points, your application will be denied.
But before you think about how many points you need to qualify, have you checked if your specific occupation is on the list of Skilled Occupation List (SOL)? Just this past July, there was a change in the list and there are 4 schedules. You must choose the one that applies to your specific situation. If you don't see your occupation in the list, then you are not eligible to apply for this visa.
If your occupation is on the list, then you are eligible to apply for this visa. Based on your calculation that you do meet the 120 points pass mark, then your next step is to have your skills assessed by the assessing authority. There is a fee for this. You will receive a letter confirming if your skills are recognized in Australia. There should be a code in this letter that you will need to document in your visa application. This is a requirement for this visa application.
One last thing. The work experience to qualify should be in your specified occupation - 3 out of the 4 years,etc.
You mentioned below that you will later on have an employer sponsored visa. If that is the case, can't you inquire from that employer of how to obtain the permanent resident visa? There is a another list called Employer Nomination Scheme Occupation List (ENSOL) that lists a bunch of occupations that employers can nominate people. There is more information in the website about this.
If you still have questions, you can visit an Australian Immigration office if you live near the Australian cities found in the website link below. I visited the Sydney office last year while vacationing accompanying someone else for their visa questions. You don't need to make an appointment. Just pick a number and wait until one of the immigration reps calls your number. Then you can ask them any questions that you may have. Just a note that from my experience in visiting the office, the immigration officer references the website to find the information that is being asked. So this means, most of the questions that people have can be found in the website directly. You may not hear anything different than what you see in the website. However, there might be issues for some people that have complicated situations.
