F1, U29 (the CUDA chip), S1, and UF8 all look like they need to be replaced. Don't know about anything else. You may have got lucky, as at least it isn't a ROM chip. Thankfully, the damage looks like it stayed pretty localized to that area and wasn't a very violent explosion.

Good luck, and if I were you and it still didn't work - try substituting it with a LC575 logic board as others have suggested.
