1. ECB is now part of CEDET, which in turn is installed in Emacs, so it can
be removed from the list of packages to install (search for "ECB").

2. The suggestion for "Save undo information" could say to use undo-tree,
which already does that. According to undo-tree.el, it's already copyright
the FSF, but it also says it's part of Emacs, which is surely false. The
author is Toby Cubitt <toby-undo-tree@dr-qubit.org>, and undo-tree's
upstream is at http://www.dr-qubit.org/git/undo-tree.git

I can make these changes if they're deemed apt.
