You will be as well using DVD+R as they hold more and if there is almost 7GB on the recovery patition, you will probably need two DVD disks.
The recovery partition is designed to hold just the info that is required to recover your system in an emergency, that is why it is that size.
Does the recovery partition have a letter like the other drives and pertitions, eg. C:\ D:\ etc. Usually it should be hidden so that nothing can be written to it or deleted from it.
No matter how full it is, it is not effecting the speed of your computer because your computer is not looking for information on it. When the laptop wants info such as from one of your My Documents folders, it knows they are stored on the C:\ drive so that is the only place it looks for it.
In Ccleaner -> Tools -> Uninstall is a list of all the programs that are installed. Have a good look through the list and uninstall any programs that you do not use any more. They may have been there from new but never used. Things like the 90 day Norton trial that you probably never activated or the 60 day Office 2007 trial. If they have expired and you are not using the full version, get rid.
Then run the Registry and cleaner in Ccleaner. Finally run a defrag on the drive.
