Something like this?

-- snip -- #!/bin/sh

TARFILE="$1" test -z "$TARFILE" && TARFILE=-

git-ls-files -z | xargs -0 rm tar xvf "$TARFILE" | xargs git add git-update-index --remove $(git-ls-files) -- snap --

Notes:
	- this updates the index to match the given tarfile, you still 
	  have to commit yourself
	- it does not handle compressed tarfiles (you have to do something
	  like "cat bla.tar.gz | gzip -d | sh git-untar.sh")
	- it does not remove empty directories (i.e. if the current index 
	  contains a file "a/b", and the tarfile does not, and the
	  directory "a" is now empty, this is not handled)
	- usually, tarfiles contain files inside a subdirectory. There is
	  no facility to strip the subdirectory
