Considering Kakashi's knowledge of the 8 Gates, he probably already knew how to use them prior to the Lee and Gaara match. It seems the only reason he unveiled the Sharingan was to keep up with Lee's speed.
not pure speculation.
kakashi uses kage bushin after he sees naruto do it, on the bridge.
kakashi uses his gates after he sees rock lee do it while rock climbing.
kakashi will use mange sharingan to rip itachi a new one (i believe oro gave kakashi the scar but itachi is my #2 man... *this is another argument).

Funny how you ignore the part where Itachi talks about his fear of Kakashi copying all his jutsus...

No. Not true. This is contrary to the entire Naruto series foolish foolish man. Every battle we have seen has been built up from the most rudimentary skills: curse seal levels, summons, berserkers.

C'mon how fucking boring would Naruto be if
Hokage went ... "guess what oro, we're skipping the entertaining playing around, I'm ending this with Fuujin right now."
or
Kakashi went "f-u Zabuza, eat raikiri NOW"
or
Naruto went "grurururur .... nine-tails .. gururururu" (ok kage bushin's suck, maybe Naruto should do this).
or
Sasuke went "Chidori in yo face mutha fucka Gaaraaaa..."
or
Haku went "ice mirrors and end this shit."
or
"Favorite sound nin" - "lvl 2 seal weeeeeee..."
and this list goes on and on...

Edit: OK enough mudslinging... so back to the task at hand
Kakashi copied Mange. We yet to see him perform it. (and now I'm thinking Sasuke probably too). Itachi got arrogant with his ability, and busted it out on Kakashi because he didn't think Kakashi will be able to do it. I might be spoiling some really awesome Kishimoto storyline - but I'm calling it right now - KAKASHI WILL MANGE SOMEONE!!!
