I'm afraid this is rather difficult without offending the thread starter, but you either haven't been understanding what Karl has been telling you or you are choosing to ignore him.
The recovery partition is used to restore your computer to its factory state i.e. exactly how it was when you first bought the computer. If you delete the recovery partition and you haven't got any recovery discs you can't recover to the factory state, which means you would have to buy a set of HP recovery discs or a Windows 7 DVD.
A restore from a system image backup restores your computer to the state it was in at the time you created your backup.
If you decide to keep the HP Recovery and HP Tools partitions you can only increase the number of partitions by creating logical partitions in your C drive.
This tutorial explains how to create a system image backup.
