I put the ports tag into a separate supfile called ports-supfile, but you've
got the right tag for inclusion in your supfile.

Yes, with a production machine

yes. you can also add some steps here for extra safety
backup /etc this cannot be underestimated if you are not confident in your
ability to recreate them from memory.

Obviously replacing <kernelname> with the name of the kernel config file you
have edited or GENERIC

drop to single user mode here with a
shutdown now from root.

Be careful here. This will merge in the new scripts and config fles in /etc
any that you have modified you will not want to automatically merge the new
files in or you will lose your changes.
Some you'll want to merge by hand.

Like Subhro said, no worries to ask questions as long as you've done your
reading. I'd suggest reading that handbook chapter again, and also reading
/usr/src/UPDATING as that file has the final say.

You're welcome, good luck
