The AE71/86 crossmember *might* fit the celica. Aside from that, you'll need AE71/86 engine mounts, EFI fuel pump, possibly a surge tank, but toyota tanks of that era were all behind the rear seat iirc. If you're unlucky you'll need bigger fuel lines. AFIK there's a bellhousing to bolt a W to an A, but I dont think there's an adaptor ring. Various GE/GZE flywheels might need to be compared to find one appropriate.
Your diff will last if it's in ok condition(no lash) and you load it up gently.
I'd find a wrecked ae71, and do some basic measurements. The crossmember might be suitable for an A as std.
Other things to keep in mind are : Inlet manifold(throttle position), clutch, clutch pedal, spigot bearing, exhaust manifold, tailshaft, and obviously wiring.
Have fun
