1. How do I number my columns like I numbered my rows?
2. Can you spot areas where this code could be written in a more optimal manner...
I'm trying to break this code up into multiple methods and I was successful with the first bit but the other two I can't seem to figure out.

This is my first "question"(?) here in code review. I'm hobbyist programmer.
My biggest weakness(and fears) is that I don't want to show my code to anybody. Because of that and lack of school/mentor my code can be bad, and I think it is.
Well this is my way face my fears, publish unfinished...

Oke, there are more points to say on this code then you imagine.
Never use static for a user/session variable.
In your VM you have the following code :
