I think you're onto something with the Alpert/Ben thing. Think about it - Alpert KNEW Locke would be coming back, and he knew from meeting him in the 50's that Locke knew who Jacob was and that Locke was the chosen one. He then started "following" Locke throughout his life, but he was never quite ready (like when Alpert had him choose from the objects he brought). So, Alpert needed a "stand in" to be leader until Locke actually was ready to come to power. Ben comes along and provides him with exactly that. Ben was young and impressionable and had been "healed" in the Temple. He wasn't truly the chosen one, but he was more in touch with the Island than the average Other (?). So, Alpert spent Ben's young years convincing him he was special and the chosen leader, all along knowing he was just biding his time until Locke came to rightfully take his place as the REAL leader! LOVE IT!
I still don't get why Ben said to apologize to Desmond. I mean, I know he shot him, but why would that be the foremost thing on Ben's mind at that point? He did a lot of bad things that he could have apologized for - why did he pick THAT one for which to beg forgiveness? What if, after he falls in the water, Ben surfaces and DOES kill Penny?
I TOTALLY thought Alex was going to kill Ben when she appeared! I was quite surprised Smokey let him live!
The "shadow of the statue" has to be the 4-toed statue, but who the heck Ilana and the other Shadow Statue Group are is a mystery! I like the idea that they are pre-Other Others, or descendants of the original Island inhabitants, but would that really make sense? A whole other set of people fighting for the Island that we haven't even heard about until now? I think they're Widmore's moles...
And one little tidbit about the preview for next week: I am thinking the person in the body bag is Juliet. There is one shot where they show a sort of blurry side shot of the face, and I swear it's her!
