On the Front id do front main and cam seals these would be difficult to change if they were to leak later and mean basically redoing the timing belt. Then rear cam seal/plug thing and dizzy seal are optional but good to do as youll already be there.

Tip would be to do it slowly and double check things like tdc on the first cylinder if you have access to cam locking tools it helps I used 2 old nails... Did the job but wasnt the greatest thing. Also if you have access to a hoist definately use it. I did mine on the ground. Not fun.
