Default Headgasket replacement - What parts are required?

I have an 07 STI with ~6k miles that needs headgaskets and am coming up with a list of parts to order for my gasket job:
- Exhaust manifold gaskets (x2) = 14038aa000
- Head gaskets (both sides) = 11044aa670
- Uppipe gasket 44022aa150
- Downpipe gasket = 44022aa180
- Cam seals (x4?) = 806732160
- Timing belt 13028aa240
- Intake manifold gaskets, lower (x2)
- Rear main seal
- Valve cover gaskets

Is there anything else I will need for the job other than fluids? I want this to be as complete as possible so I don't have to mess around with this again.

Any oil gets on the timing belt, it needs to be replaced. I've had this confirmed by several Subaru mechanics (friends, not just dealership guys trying to take my money). I don't know about you, but I'd rather not have a $100 part cause my $6000 engine to fail. The same goes for any gasket/seal so they might as well be replaced if the job is being done. Nothing like trying to save $4 by not replacing a seal while you're there (that's hard to get at to boot).

duh.

As mentioned, don't bother replacing the seals since they're brand new. You don't need to replace the timing belt. I also wouldn't have an issue reusing the downpipe or mainfold gaskets, they rarely leak. Replace the upppipe gasket though.

I have been told by numerous subaru mechanics (or ex subaru mechanics) that those pieces should be replaced whenever they come into contact with any oils. If there was oil on my fingers, it will lead to improper wear (and hardening) of the belt and can cause skipping. I'd rather not have a $100 timing belt cause my $6000 engine to be destroyed. As for the gaskets, I never reuse gaskets, ever.

You could wash your hands or wear gloves and save the 100 dollars on the belt. I've taken mine apart more times than I'd like to count on my race car playing with different oil pumps and have never replaced it. At 6K, you're just throwing money away. By your logic, just a little bit of oil on your hands when installing a brand new belt could cause it to fail. If you apply to same car to removing the old belt to avoid getting oil on it that you were planning on applying to the new belt you'll be fine.
