For what it's worth, I've seen cars (especially as old as yours) with damage such as you've described, declared "totaled" by insurance companies.. I assume you don't have full coverage insurance.
In order to get it drivable, you probably will have to put it on a frame straightener, in order to get the suspension mounting points lined up for proper geometry, before you can even start trying to replace parts. That alone can be pretty expensive.
You might actually want to consider parting the car out if it's too expensive for you to fix it. Good used parts command a premium price these days on places like eBay, since there are so many of these aging cars still on the road today.
