Umm, I think you are confusing the "resize2fs" utility and the various
derivatives of "parted"....  It is "parted" that cannot handle some of
the newer flags applied to ext3 filesystems, like "sparse_super"....
"resize2fs" is one of the utilities that we use to resize filesystems
with LVM (or "ext2online")....  It tends to work more often than not,
but does require a full e2fsck prior to "shrinking"....

The real problem for the OP, is to:

1) Shrink the second partition/filesystem
2) Move it to the end of the old range (leaving a gap between
partitions)
3) Grow the first partition/filesystem (utilizing the gap)

All of this is more involved than should be normally attempted,
particularly since the OP is confusing terms like "partition" and
"disk".  So I would agree with your later recommendation to backup,
recreate, restore....
