Without any pictures up yet, it's hard to determine exactly what you'll need to replace. Going off your list, though, I have this:
-Driver's side curtain air bag ~$100
-Driver's door ~$200
-Driver's side rear door ~$200
-Tail light ~$100
-Tire (If your tires are at all worn, you'll need to replace all 4 to avoid extra wear on your QDII system) ~$200-$800
This should all be replaceable at home, though unless you have a tire mounting machine you'll have to go into a shop for that. I priced the air bag and doors at what I could find on eBay, and didn't factor in shipping. Just off these numbers, you'll be looking at $900 or more, up to around $2k with shipping and all 4 tires factored in.
You'll also need to get estimates from a body shop about the door brace, though I imagine it isn't particularly important structurally.
As far as cosmetic problems, I'd leave those alone. A body shop could easily charge you thousands to repair those. You could also look into paintless dent repair if you want to fix them without having to repaint.
If you can come up with the money to replace all of that, I think it would be a good option. It'll allow you to keep a pretty reliable vehicle with plenty of mileage left in it.
However, if fixing it isn't in the cards, I'd imagine if you were to try selling it as is, you'd get $5k or less. You're not gonna get your money back on the new transmission or OME lift, and an '06 with 140k miles on it is worth $8k in perfect condition. A wrecked one won't be worth much at all.
