What is the best ROS version to install (and if not Lunar how hard it is to re-install the correct version)?

Tony,
To be compatible with the group project, you want to install ROS Kinetic.
You can install Kinetic *in addition* to your Lunar installation. That's one more elegant thing about ROS-- coexistence of distributions.
The ROS code base for a distribution lives in a subdirectory under /opt/ros. So you can have /opt/ros/lunar and opt/ros/kinetic happily living side-by-side.
The actual ROS installation that is "active" is determined by a line written into your ~/.bashrc shell setup file (which is automatically run each time you open a terminal to set things up).
You will see a line like this if you open ~/.bashrc in an editor:
source /opt/ros/kinetic/setup.bash
The above line will be added to your ~/.bashrc script when you install ROS Kinetic. You probably should comment-out (put a '#' at the front of) the similar line written for ROS Lunar to avoid confusion later.
If this info is not complete enough. please follow up with another post.

You can have both Kinetic and Lunar installed - kinetic is installed in /opt/ros/kinetic/ and lunar in /opt/ros/lunar/
Isn't lunar still in development?

Lunar was officially released almost a year ago. http://wiki.ros.org/lunar
From the ROS Distributions page http://wiki.ros.org/Distributions :
You might have been thinking about these fixes being applied to Lunar.
From the ROS Distributions page http://wiki.ros.org/Distributions :
once a distribution is released, we try to limit changes to bug fixes and non-breaking improvements for the core packages (every thing under ros-desktop-full). And generally that applies to the whole community, but for "higher" level packages, the rules are less strict, and so it falls to the maintainers of a given package to avoid breaking changes.
