Swapping in a 4th 3sgte soon, Need advice on what's needed to be done before dropping in Options

[ILoveMySilly97]

I'm planning on swapping in a 4th gen 3sgte and want to know what's recommended to be swapped or replaced or repaired while the engine is still out? Is the waterpump interchangeable with the 5sfe? Should I replace the oil pump seal and pulley seal? I know they're a common leak on a 5sfe. Here's the list I've made talking to a friend of mine with a st184 4th gen swap.

Interchangeable with 2nd gen

Front main seal #90311A0005
Rear main seal #9008031073
Alternator belt #909160229377
Power steering #99363-70760-83
Cam seals #9031135040

Injector Seals – 2zzge - 9030107024

Timing Belt – 3rd gen - 13568-79105

Wire - Wiregap
Clutch Kit – SouthBend
Oil – 10w30
Spark Plug – NGK Iridium BKR7EIX

Looks like the water pump (16100-79225) was only used in the 4th gen 3S-GTE and all three variations of the BEAMS, so you may need to special order that from Lithia. I'd add a valve cover gasket and spark plug seals too. If you're going to replace the oil pump seals, you may as well just replace the pump so you know it's new. You'll more than likely need new front and rear motor mounts unless they've already been replaced. If you can find a set, it would be a good idea to have spare coil packs on hand but you won't immediately need them for the swap. I went ahead and replaced my radiator and axles during the swap but that's not necessary either. I know I'm missing some things but I'm at work and my brain isn't functioning properly.
