If you go 2.8, you're going to want bigger turbos. Scratch that. If you go 2.8, you're going to want one single larger turbo. -
Definitely the stroker kit. once you mention you have a RB28 everyone will assume you will flog them and hopefully won't start asking about support mods. Anyone will be too scared to race you, except maybe the RB30 boys -

Just a quick update: I decided to go ahead with the de-cat for now. The exhaust shop inspected the catalytic converter and said it was in good condition. I took a look myself, and it does not appear broken nor clogged. After the de-cat, the car feels more responsive and smoother. The shop also reinstalled the exhaust temperature sensor into the de-cat pipe, and now the warning light no longer comes on, even when driving hard. The only thing that’s bugging me is the tinny, “can-like” sound the exhaust makes now (similar to having a hole in the muffler). The shop suggested that I might need to replace the muffler. I'll have to think on what to do next. -

I want to start upgrading but don't have the budget to drop 15k at once, if i was to do one first which would be better and why? -
Yuh. It is very rare for a single turbo to throw ceramic into the engine. Quite common on GTRs. As I posted above. Mine did destroy the O2 sensor on the way out though! Plastic compressor is fine with the temperature. It's not some flimsy PE/PET/PP thermoplastic. It's a thermoset resin with reinforcing material in it (a composite, as posted by @Lithium above). The compressor never sees much more than 100°C because it's never boosting very high. If you boost it high enough to make a lot of temperature, then the turbine will depart the scene and stop the party anyway.
