That is by design. As at 8.04 or 10.04 (the last time I looked), NM
will ignore any interfaces specified in interfaces(5). It makes sense
that if a fresh install is to have NM, it should lack interfaces(5)
entries.

In case anybody hasn't realized it, "remove" leaves config files around
(including e.g. init files), which is a little icky and a (probably
negligible) performance hit. Use "purge" to get rid of those as well.
aptitude search ~c # lists removed-but-not-purged packages.

See also "resolvconf" package if you have >1 system writing to
resolv.conf (e.g. two PPPoEs, or DHCP + OpenVPN).

IMO you want both "allow-auto eth0" and "allow-hotplug eth0", although
the latter is completely ignored on Ubuntu systems because the udev
script that implements it is missing. Presumably NM is expected to
replace that.
Also you can write >1 on a single line, so instead of
auto foo
iface foo ...
auto bar
iface bar ...
I prefer
allow-auto foo bar baz quux
allow-hotplug foo bar baz quux
iface foo ...
iface bar ...

At the boot: prompt of the installer, pass desktop=lxde.
During the install the tasksel task prompts for something like "desktop
environment" -- which one you get is goverend by the desktop= option,
which almost certainly also has a debconf/preseed longhand form that I'm
too lazy to look up. See also F1...FN help screens, see also
amd64-installation-guide (or whatever arch) package, also available on
debian.org website somewhere.
I also highly recommend theme=dark during the installation.
