how much red tape it is depends on what state you're in (except for passport since that's federal), but all of these documents are replacable. your birth state probably has a page on how to get a new copy of your birth cert, and the court that did your name change still has that in their records and will send you one for a fee if you call them i believe. either that or that's another thing the state keeps a record of. honestly that also depends on the state lol

EITHER WAY there are avenues to get all of these. like peoples' houses burn down documents are lost all the time
