Yeah, and they fit great, too.

Don't worry about the stock airbox, so long as you have the MAF - the stock one really doesn't (IMO) work very well in our engine bays. I used the inlet elbow from a 2004 GTO, put that directly on the TB, with the MAF on the other end, and a K&N directly on the MAF.

Fuel...I don't know if the '01 uses it, but the '00 mine is from used a 'returnless' fuel rail at the engine, so your regulator should be somewhere else in the system. I used a GM combination filter/regulator (it's for either the '97 or '98 Corvette, I don't recall at the moment) to take care of this. Also, I'm using the stock tank, with an external Walbro GSL392 mounted on the framerail.
