Water pump may be worth a look, but be careful as some of the bolts like to sieze into the head sometimes & snap off

If you aren't splitiing the engine then don't worry about the timing chain, deffo do the clutch & maybe a lightened flywheel ?
As James said, maybe the mounts while you're there & check for oil leaks, if it looks like it's leaking from anywhere you may as well replace gaskets etc. easier when out, especially the timing chain cover & sump U seals !
