Right, this is a use-case I also commonly have, and nowadays I
mostly use the rebase -i approach already described, combined with
the use of git-gui for easy selection.

One additional trick I sometimes use, when I have reordered/squashed/split
a couple of commits, is things like "git checkout @{1}" to catch any missing
changes I could have lost while working.

Some time ago I was using stgit extensively, and had developped
a couple of scripts to support that workflow.  You will find them
in the contrib/ directory of the stgit repo, and in the
stgit-contrib debian package.  Note that I did not use them much
lately, and they may need some tweeking to work with recent
git/stgit.

The still-relevant scripts are:
  * stg-fold-files-from: pick specific hunks from another patch up the stack
  * stg-dispatch: dispatch specific hunks into another patch down the stack
