I want to shrink my /dev/sda1 partition but gparted will not let me do any editing and alterations to anything. Note that everything is in gray, so that I cannot edit anything. How can I fix this? I'm using an HP 635 Notebook PC for the record. Thanks. note the gray areas

All the options are grayed out because the partition you're trying to resize is mounted and is a root partition. Any partition has to be unmounted before resize/move/delete and there's no way to unmount root partition while running Ubuntu. Whereas you can mount other partitions by simply right click and select unmount. So boot from a Live CD/USB and then you can resize the root partition but make sure to backup you data before doing so.
