Green Arrow started as a complete cypher, but he is almost three-dimensional now. This is almost exclusively the result of his adventures slowly effecting his character over time.

I do believe that his version of GA didn’t use trick arrows way back when."

Yes, Mike Grell establishes in Green Arrow: The Longbow Hunters that Oliver gave up the trick arrows because he came to rely on them too much and lost his edge as an archer. There's a prominent image of a bunch of his trick arrows--including the boxing glove one--sticking out of a garbage can.

(However in Grell's prequel mini-series Green Arrow: The Wonder Year, Oliver does use a trick arrow that he unintentionally created while target practicing--an arrow with a golf ball stuck on the end of it--which he shoots into a thief's groin, although he was aiming at the man's head.)

It was Mike Gold, Grell's editor, who came up with the idea of Green Arrow as an "urban hunter," keeping him out of the DC Universe proper to fight real world criminals such as corrupt businessmen, street gangs and serial killers, as well as CIA spooks and Yakuza assassins, on the streets of Seattle. The trick arrows didn't fit the tone of the series.

The series also didn't establish a rogue's gallery either (ninja archer Shado and hitman-for-hire Eddie Fyers started off as Oliver's adversaries, only to become his allies later on), a continuing element of his storytelling engine as John pointed out.

When Denny O'Neil developed Oliver's left-wing personality in the pages of Green Lantern for the Hard Traveling Heroes stories, GA was standing up for the little guy and fighting real world villains. O'Neil set the stage with late 60's-early 70's social issues that paved the way for Grell to tackle those of the late 80's-early 90's. It is these stories where Oliver came into his own as a character and not just a second-rate Batman. Where Batman's mission is truly to put fear into the hearts of criminals, helping the innocent is more of a by-product of his actions whereas Oliver focuses on the well-being of society's victims. GA revels in the swashbuckling of battle while Batman thrives on dealing out punishment.

So even though the latest series devised a rogue's gallery for GA including Count Vertigo (originally introduced as a GA adversary in Mike W. Barr's 1983 mini-series, but that was for one issue only, as Oliver's real adversary in the story was corporate corruption--did GA ever confront him again between Barr's story and this series?), Brick, Onomatopoeia (has he even appeared since Smith's run?), Merlyn, and Deathstroke (who actually was introduced into GA by Alan Grant in the post-Grell series), I'm not sure supervillains really work as part of GA's storytelling engine. Regardless, none of them have developed a relationship to Oliver as being his greatest enemy--no Lex Luthor to his Superman, no Joker to his Batman.

Oliver's greatest enemy is social injustice, and it is his calling to right those wrongs. He is the conscience of the Justice League, and as Batman said in Justice League Unlimited, Oliver's job is to keep them honest and remind them that their responsibility is to the people who depend on them.

I’m SO disappointed to find out the cat arrow was just a stuffed cat.

I know!!! At least Adam West had the decency to use live cats for his Cat Launcher!

And John... I think you forgot about Ollie's classic Nose Picking Arrow (just sayin').

Family Guy - Adam West's Cat Launcher

I do believe that his version of GA didn't use trick arrows way back when.

Tell me the bad guys wouldn't run.
