Migrating data off a failing drive

Recently one of my hard drives developed bad sectors. I have asked for
RMA and the manufacturer has shipped the new drive. I am expecting
delivery this Monday.
Now my question is, what would be the best way to migrate the data to
the new drive? My confusion is at 2 steps:
1) I have an LVM spanning the entire physical volume, created while
installing Fedora from the Live CD. So what are the proper sequence
of steps to create a new LVM on a new drive? Is the following
1. create a physical volume with pvcreate
2. create an LVM on that physical volume with lvcreate
2) After I have created the new LVM, do I just simply mount it and
copy the data off my faulty partition with something like rsync?
(my backups are couple of months old :( , so would prefer to keep the
latest data). I am asking as I am not sure how the bad sectors
might affect the copied data and the new drive.
Thanks for any inputs.
