Why not a newer release of Lubuntu? I'm sure you have your reasons. But in case you do want to go with a newer release, as stated in the answer the screens are pretty much the same, they may just look a little different
You can use ImageBurn under Windows, to burn a bootable CD/DVD, and Unetbootin for a bootable USB under Windows, and Linux. I would recommend that you create a bootable USB. For burning a CD/DVD under Ubunut see How to burn a DVD on Ubuntu
If the CD writing fails, try writing at a slower speed. For better
results, try the slowest burn speed reasonably possible. This is the
single most likely cause of problems but is much more widely known
than Md5sum/SHA error-checking. Slower speeds ensure greater accuracy.
Once you burn the CD/DVD, check it and make sure that it was burned
perfectly, by doing a CDIntegrityCheck
First of all why use an alternate CD? Just download the regular CD. For Lubuntu 11.10, 12.04/12.10, and 13.04. Once downloaded you can either create a CD/DVD, or a bootable USB. I would recommend that you do an MD5SUM on the ISO downloaded, and try burning on a slow speed, just to be on the safe side.
When done, just change the boot order in your system's BIOS to boot from the desired location. Once the installation starts, just follow the screens as shown in the images below. These steps are for all the release mentioned in this answer. The screens are the same in a way, but look cosmetically different from one release to the next.
