What other gaskets besides headgasket need replacing?

I believe the timing chain (and it's components) need changing in my
1995 Toyota 4-Runner,22R-E with 227 000 KM. I am aware that there are
two ways to change the timing chain parts leaving the cylinder head on
which is easier but timing cover may leak oil at the top where it
meets headgasket or remove cylinder head.

If I remove the cylinder head which other gaskets would I need to
purchase alone with the headgasket when replacing timing chain
components?. Should the intake and exhaust manifolds remain on the
head? or will the whole cylinder head assembly be too heavy to lift?.

I will be reading the timing chain replacement write up articles below
again:

I also will be reading the FSM (factory service manual) section on the
timing chain replacement again:

I will spray the hardware with a deep penetrating lube 1 day in
advance and again hours prior too.I will take a piece of cardboard and
make a shape of timing cover and poke the bolts through each spot.

Any other piece of good advice?.Thanks in advance for help/replies.
