I don't know that I'd consider "Punch it!" specific enough to credit as a Star Wars "reference." Sure, Han Solo says it memorably, but it's rather obscure and using the statement in that context doesn't solely originate from the Star Wars films.
By the same token, the bit
Jarod mentioned upthread about the Enterprise's arrival at the final showdown:
And the scene where the Enterprise suddenly appears to save Spock from the missiles was pretty much staged like the Falcon's sudden appearance during the battle of Yavin.
Maybe that scene
is staged just so as a conscious nod to
Star Wars--I'm just fine with it if it is--but the
Millennium Falcon's sudden appearance in that movie was really nothing far removed from what happened in the last reel of countless old Saturday-matinee Westerns when the US Cavalry rides over the hill, just in the nick of time, to save the day (and our hero.) It's "the good guys to the rescue" - it's a
trope, not anything which originated with Lucas and
Star Wars.
Besides...
James T. Kirk said:
Whatever happens, Mister Sulu, if you think
you have the tactical advantage, you fire on
that ship, even if we're still on board. That's
an order.
...they were only following orders given earlier in the movie.
