You won't be able to install anything on a new SSD, until you erase the SSD first.
I'm assuming that your "original download disk" is Snow Leopard (last OS X version on a DVD disk)
So, steps are:
Boot to your installer disk.
Open Disk Utility, and erase the new SSD. You can name it something memorable, like MacTheKraken
After you have erased the SSD, Quit Disk Utility, and continue with the OS X install, using your newly erased SSD as the destination.
That will give you your OS X system, and you can go on from there.
You have no backup of any files or pictures/music, so if the HDD is dead, there's not much more you can do, except go through the new user setup, and go ahead to use the system that you install from the DVD.
You could help by telling us which MacBook you have. For example, you can search for a site that will
decode your MacBook's serial number, which will tell you exactly what model it is. From that, we can tell you what OS X version you COULD upgrade to. An older MacBook from 2006 might be limited to Snow Leopard as a maximum system.
