Sounds like a straight forward job for gparted.

You may need to boot from a run-live to do it, so the file systems are
not mounted.  You can do it manually with resize2fs and others but if
you don't really REALLY know what you are doing, it can be a receipe for
disaster.  Highly recommend going the gparted route.  It will be time
consuming, if you are moving the start point of an existing partition,
then it can become very time consuming, especially expanding a partition
and moving it up on the disk.  Just deal.  It will cost you some time to
let gparted redo the partitioning but it will be done correctly.  It
will also deal with resizing the file systems if you don't have anything
real bizzare.
