1. fsck won't do anything at the lower level of partitioning.
2. A few years ago I personally tested this, and yes, an aligned partition
*does* make a significant difference in access time.
3. I've only used gparted once or twice. In user-surly parted, you want to
run it as
      $ parted -a opt /dev/sdc
    then, when mkpart, be sure to use start and end as something like
x.0GB, +x.0GB,
    and parted will do the alignment correctly. (As opposed to only
telling you
    that the alignment is not optimal, rather than *telling* you what you
should be
    doing to make it optimal.)
