Hi Spark!
I'm getting ready to post part 3 right now.
No, Lana doesn't know about Clark. He hasn't told her yet. His mother points that out in the second part - that maybe Lana wouldn't pick on certain things or cut him a little slack if he told her.
Remember in this story he's not Superman yet. He only helps out when he can, so there's really no reason for Lana to suspect anything. It's not like she can look past the glasses to see the man in the Red and Blue suit... there is no man in the Red and Blue suit... yet.
