bq.  there must be some way to just get the checkout sha once

This will work on the current branch:

{code}git log --format="%H" -n 1{code}

But also this, for example for the trunk branch:

{code}cat .git/refs/heads/trunk{code}

This is why branching in git it so cheap, a branch is no more than a file with 
a sha1.

bq. the command line of Git is the most confusing an user-unfriendly thing

Indeed, and this makes the learning curve steeper than it would need to be.
