Answer 1

My guess is that on step 2.6.2 Edit /etc/sysconfig/grub you copied the example line verbatim instead of adapting it to your system:

## Example row ##
GRUB_CMDLINE_LINUX="rd.lvm.lv=fedora/swap rd.lvm.lv=fedora/root rhgb quiet rd.driver.blacklist=nouveau"

You should only append rd.driver.blacklist=nouveau to end of the existing GRUB_CMDLINE_LINUX=”…” line.
