I have searched and have not been able to find an answer.

I have a freeze plug leaking on the passenger side, I think the front plug. I don't think I can get to it without removing the exhaust manifold. Plus I want to replace them all on that side.
I know I will need a gasket between the head and the manifold, but what other gaskets do I need and do I remove it with the turbo attached?
Are there any parts websites with exploded parts diagrams?
I plan to take pics and will add to an existing freeze plug thread if applicable.
