The aftermarket parts for this swap aren't bad, but I wouldn't blame you for getting factory fenders. Get the rest of the stuff aftermarket, though- the grilles are nice, the headlights are glass... don't spend more on used OEM parts!
As for the core support, that's your call- if yours is in good shape, just modify it to fit the 4Runner headlights- I've seen a bunch, and it's a fairly easy mod. If yours is banged up, then go ahead and swap it to make your life easier.
The A/C condenser and the receiver/drier (if you have A/C, of course) will be in the way of your headlight bracket, so be ready to relocate it a bit.
Good luck with the swap- they look great!
