[development] Temporary form data storage ... and avoiding validation

I'm using a module-generated form in a mode like a shopping cart, where
the user can add data to it, go to other pages, and come back to it, and
the data persists.
At first I wasn't submitting the data until it was time to complete the
process, and so, to persist the data, I was using variable_get/set
because without the form being submitted, nothing was being persisted in
form_state. However, I've since switched to each of the buttons (return
to other pages, update form, submit) causing a submit, with varying
logic based on which button was clicked. I discovered (duh!) that
variable_set/get was a poor idea, because two users online at the same
time end up would get each other's persisted data on the form.
So, two questions. Is form_state going to persist the user data for me
between form loads, or is there a better method? And I've run into an
interesting problem in that the portion of the form with required fields
(name, etc) doesn't need to be filled in until the user wants to submit,
but of course, that ends up throwing an error when the form is
'submitted' due to one of the other buttons being clicked. Is there a
way to have those buttons cause a submit, but bypass validation?
