I would like to resize /dev/sda1 partition

Answer 1

As /dev/sda1 is your boot partition, you are not going to want to resize it while the system is live, nor would be likely able to.

For your best bang for your buck, use GParted. It's a dedicated distribution which boots to a minimal GUI specifically for resizing and moving partitions around. It will handle all aspects of the resizing for you, including defragmenting (when moving NTFS or FAT partitions), shrinking partitions prior to a move (if required), and expanding the partition to fill the space available on the drive.
