Run the following command in terminal:
sudo apt-get install lubuntu-desktop
This may change the GUI to a lightweight Graphical interface. Although it DOES NOT make it Lubuntu.
Lubuntu has less services, less resource consuming applications, and an overall smaller size when compared to Ubuntu.
GRUB 2 will recognize the system installed; I believe the root question is:
"Can I replace my current Linux install with Lubuntu, keeping the current partitions and data intact?"
The answer is Yes.
Once you boot from the Lubuntu Live CD and choose to install, Lubuntu will recognize this install and ask you if you wish to replace with Lubuntu 'keeping data where it can' and erase everything else.
I suggest the tech savvy individuals to play with Grub in a VM before attempting anything of this nature on your real system, and also of course backing up everything. It gets confusing when dealing with multiple installs, where to install Grub and mount points. Boot manager inside Linux can help after an install as well.
If you are somewhat tech savvy I also suggest creating your own partitions manually in the future with a /home
directory; use Gparted to see how Ubuntu has currently setup your HDD and use that as a template to improve upon.
In your case the memory of your system is too low for the Lubuntu GUI install as 256MB is recommended if I recall. But hopefully this will help someone else with a similar issue.
No.
Unlike Ubuntu, Lubuntu 12.04 is not a LTS, this version will be supported for 18 months. However, a lot of work has been done to improve the stability of the system.

Note: Lubuntu 12.04 is not LTS, but it's based on Ubuntu 12.04 LTS. So it's very stable, the same way as Ubuntu 12.04 LTS. I'd like to recommend to you to upgrade your system to Lubuntu 12.10.
You can check the differences of Lubuntu 12.10 to Lubuntu 12.04 at this link.
