tftpd speaks tftp, vsftpd speaks ftp, these are two different protocols,
both daemons run on different ports

to enable PXE boot, you need to specifiy a next-server and a filename in
the dhcpd.conf. you can set them on a global level or only for specific
NIC vendors or subnets or whatever. However, no client will get that if
they never boot from their network card. example is here:

I've got a script collection which builds a customized ISO, you can find
that here: https://github.com/virtapi/LARS/
there is also a script that automatically extracts the ISO:

I would not use xinted but run them standalone or through systemd, but
just a personal opinion. your setup will also work.

You may want to check the README.md in these 4 projects, they describe
how you build your setup (and a bit more): https://github.com/virtapi
I'm always reachable as bastelfreak in #archlinux.de, just let me know
if you've got any question. I built probably the exact setup you want a
few days back.
