Raimi told about 2 years ago that he would release an extended cut, called Spider-Man 2.5, on DVD. It never happened.
Now this looks promising. I have collected some deleted scenes from the first 2 Spider-Man movies. You can see pics of them here:

and some other JJJ scene
JJJ finds Peter's clothes at the Bugle,where obviously he ditched them changing into Spidey.:
Hoffman goes by with peter;\'s clthes, and jjj says something like what's that, and hoffman says. "peter parkers pants. and his shirt and tie and shoes and socks." then jjj says, "Who does he think he is, tarzan? what is he, running around the town naked?"
