You have a good lineup ahead of you. The flex will be easy to use and the sip plus the p0106ff will remove all those swirls and light scratches. Just make sure you are working with halogen lights or a brinkmann dual xenon so you can make sure that you are ridding your car of imperfections.
Make sure you also clay the car before polishing.
Also make sure you are breaking down the polish completely, yes it will take a long time but it will be worth it.
However, I would not bother using a glaze after polishing. A glaze just fills in imperfections and hides swirls and scratches from the paint. Since you are polishing the car with an aggressive polish followed by a finishing polish there shouldn't be much to hide. I would use the glaze if you feel that you will have trouble removing all the imperfections. That way you will feel more satisfactory with your work.
Another thing is if you use a sealant to protect the paint which will last anywhere from 3 to 6 months there really isn't any point of adding the additional souveran wax. Adding the souveran may bring out the extra depth and wetness of the paint but it won't do much for protection. If you do feel you want the desired results then make sure you apply the souveran a minimum of 24 hours after applying sealant.
Make sure you take your time, going slow to properly remove perfections. Good luck
