You can choose between ALSA sound system or the more advanced Jack sound
server. I would recommend using ALSA for now. Select that as your "audio
system" when creating a new Ardour session. Something like 44.1khz, 1024
buffer and 2 periods should be fine for most internal audio cards.
Later, you can play with Jack. Use qjackctl to manage jackd, it makes it
easy to view your application sound routing and change settings. Also,
if you have two jack compatible softwares you can use jack to start both
applications. An example would be to use one application to play a
composition or a video and another to record. Jack can start the
recording and playing at the same time and handle all the routing as
well. Very cool stuff can be done with Jack.

This might help you get started https://www.youtube.com/watch?v=arvPwZlU1ak

Yes, ardour with xjadeo seems like a perfect solution for your use case.
"Session" -> "Open Video.." This will import your video and add it to
your audio timeline so you can do voice overs and back tracks in sync
with your vid, etc.

Your phone and laptop mic are not going to sound very good. You might be
able to fix this with some filters (normalize, eq, compression). I only
recommend the H2 because it sounds great and is portable and simple to use.
You should look into condenser microphones for recording onto your
laptop (ardour) directly. Maybe someone else has some experience with a
inexpensive setup. I have a maudio fast track pro, it has phantom power
for the mic. All this stuff can be found second hand for fairly cheap,
just be careful for compatibility with gnulinux when buying audio
interfaces. I know maudio is usually supported. I'm sure there is more
supported hardware than when I was shopping for this stuff. The
manufacturer won't be much help in this regard, so you might need to dig
around the forums or try it yourself.
windscreens are your friend ;-)
