It's better to be safe and run the partitioning tool from a LiveCD or other boot-disk. You'll want a Ubuntu LiveCD of the type of Ubuntu you have installed.
To resize the Linux partitions, you want to use the Gparted/Partition Editor to do the resizing it helps to have the visual guide.
You want to use the LiveCD because you can't work on a partition that is 'mounted', which means one the computer is currently working with or looking at.
