Do remember that in the comics (specially the John Byrne revision in 86) Clark was nowhere near as serious as Superman turned out to be. He actually used his superpowers to become a football legend and win the heart of the most popular girl in town (Lana).
So the more "shallow" Clark appears to be now, the more amazing his rise as Superman will be.
But I do not see him as being shallow. When Ryan was kidnapped (in the episode "Ryan"), Clark went "damn the torpedos" and races the kid outta there. When Lana and Chloe started treating him oddly (in the episode where Johnathan Taylor Thomas could divide himself), his last line to them was incredible: "Stop treating me like the angry boyfriend, since none of us actually dated". That kind of commanding stance is the first step in his evolving super persona.
Lex, forgotten? Almost every show we get a glimpse of what's to come: Ryan and Lex talking about comic book hero "Warrior Angel" and how WA's best friend became his enemy for not agreeing to use their powers to rule mankind; Clark being told that Numan (the prophesised baby-clark from the stars) was going to battle the great evil serpent that was once his best friend.

With Christopher Reeve joining the cast and shedding some light on Clark's origin (it's told that Reeve adds two very important superman-terms to the show; my guesses are Krypton and kryptonite), it'll become a major turning point in Clark's life, towards his super-self.
Oh, and Chloe? She's Lois Lane's cousin.
How's THAT?
