I have added most of Marek's suggestions. I don't know how to solve the markdown HTML and formatting issue. (I believe alert boxes are great and should be used to make it more visually appealing but alas, it may be a bit too late to settle on this)
1 - Inform the user how to return to installation @ step 8;
2 - Clarify the need to choose a FS and format prior to assigning the mount points (option is greyed out until you do). @ step 9
3 - Guide the user on navigating the quirky behaviour of Anaconda on that part - You have to first check the box, then choose FS, then enter mount point, from bottom to top, which is not really friendly. @ step 9
Future TODO: Include details for GPT / UEFI disks. Boot mount point and FS are different, as well as the disk initialization part with fdisk (step 2).
