No, they are not identical. Comment outputs a comment environment to
LaTeX, LyX Note just omits the contents.
The comment environment that is output for comments is verbatim and
cannot be handled by a normal beamer frame. You need to pass the frame
option "fragile" in order to make it work. This disables some features
such as overlays (but I suppose you don't need overlays in a poster
anyway).
Please refer to the beamer manual, sec. 12.9 ("Verbatim and Fragile
Text"), for details.

It cannot be imported as such, since beamer lists are quite specially
defined. You'd need to set up a specific new list in beamer, using all
the beamertemplates involved in such a definition.
Since the main feature of the lyxlist, setting the label width, is
already provided by beamer's description, I do not see the need to do
that.

It tells you (in rather cryptical words, though) that the font you are
using (Utopia = futs) does not contain the right arrow symbol.
An easy workaround is to redefine the \textrightarrow command in the
preamble and make it output a math arrow:
\renewcommand{\textrightarrow}{$\rightarrow$}
