While you can get all the orders you want, that doesn't mean your STBX will actually adhere to them and stop spending... so try to protect yourself.
Absolutely.
You served him with S papers - so you are considered to be legally S'ed, yes? If so, then I think whatever debt he incurs after your LS date is solely his and you are protected from such debt.
Again, as inspiredjulie pointed out, there's no guarantee he won't spend community money on stuff other than the necessary living expenses. If he does do that, I'm not sure what the 'penalty' would be, if any. I would think he'd probably be ordered by the court to pay that back to you. No guarantee of that happening either though.
Not sure how much help this is, so be sure to ask your L. Write your questions down before you go to the appt so you won't forget anything.
Good luck.
