If you want to know what parts you NEED to upgrade all it take is a few datalogs.
Do you need a higher output Low Pressure Fuel Pump (LPFP, in the fuel tank); monitor fuel pressure
Do you need a better intercooler; log Intake Air Tempreture
Do you need Downpipes; datalog Wastegate Duty Cycle (WGDC)
Do you need an intake of fancy air filter; datalog WGDC
Do you have a boost leak; datalog Long Term Fuel Trims (LTFT bank1, bank 2)
etc.
It really does not make sense to replace parts you don't NEED to. Though this has been covered many times over it's often forgotten of overlooked, the recommended parts for Stage 1, 2, 3, etc are due to the tune setting possibly overcoming the stock sensor limits. For instance, adding boost may cause the WGDC to limit out, then a code will be thrown for overboost and the car will go into limp mode. On some cars, in better condition, this may not happen. On cars with higher miles or in poorer condition it will happen.
Asking for parts upgrades is just covering bases to ensure there are no problems.
You're best bet is to judge what you want out of the car and what your intent for it is. If you do racing, then it's pretty obvious you'll want to upgrade parts. If you're just in it to spend money for scene points, I don't know what to tell you, maybe just add more stickers?

Valid points :-)
No, I'm not in it for scene points, more the opposite really. I'm a 47 year old with a mid life crisis...lol.
I came from the Mazdaspeed scene, had a speed6 which "required" certain upgrades to avoid others causing major problems. For example, just replacing the downpipe would cause the fuel pump to be overwhelmed, run lean and vent the block in cylinder 3. Seems that this platform is less vulnerable to issues like that, I'm just trying to cover my bases knowing that all the parts I add will in some way benefit the car, if not actually necessary.
The FMIC is a case in point I guess. I don't think I actually need one for stage 2, I'm not tracking the car, unlikely I will have sustained periods of boost where IAT's become an issue, but if one comes along at the right price I'll buy it since a) it does no harm to and b) I can always sell it again later if I stock the car out to trade it etc.
Now....about those stickers ;-)
