Correct. You don't have to remove the Org-mode that comes with Emacs
via Ubuntu. You just need to download the new archive (or clone with
git) and have that in your load path. My setup as the first lines in
.emacs:

;; set load paths
;; set load dirs and global config options
(add-to-list 'load-path "~/.elisp/org.git/lisp/")
(add-to-list 'load-path "~/.elisp/org.git/contrib/lisp")

Replace "~/.elisp/org.git/lisp" with wherever you unzip or untar the
archive to if you go that route. Just make sure it points to the lisp
folder inside the top level folder.

pdflatex and texi2dvi are provided by a TeX/LaTeX distribution; they
are not packages themselves. TexLive is the way most Linux users roll
from my experience and reading on the web when I went to install. See
this for help:
- https://help.ubuntu.com/community/LaTeX

From that article, looks like they may recommend installing directly
from TexLive vs. using the Ubuntu package. I used to use Arch Linux's
package and then got burned by the annual upgrade as the location of
files changes sometimes from year to year and you can end up with a
borked system since the package will put LaTeX install files all
around your system (/usr/lib, /etc, /usr/local, ...). Now I choose to
install by hand via the tl-install script and structure it like this:
- System files: ~/.texlive/YYYY (as of now, I have ~/.texlive/2012)
- Local stuff: ~/.texlive/texmf-local

You can set those quite easily during the tl-install procedure (I
chose `tl-install -gui text`). You just change the main TEXDIR option
to point where you want it to go. I changed it from
/usr/local/texlive/2012 to /home/username/.texlive/2012 and then
changed TEXMFLOCAL to /home/username/.texlive/texmf-local.

I'm not sure if I customized TEXMFHOME. I don't think I use it and
don't have a ~/texmf directory, nor, from looking at my directory
structure, something like it inside of one of the other two.


Hope that helps!
