My New Classroom - The Before Shot

I got to go into my new classroom on Friday.  This is what it looked like when I came in.  If I had been smart, (and didn't have three of my boys in tow) I might have taken pictures of all angles, but I didn't.  It is much bigger than my old classroom, and I actually have 4 walls instead of a slider thing. 

When I first arrived all of the tables (all tables, no desks in this room) were up against the wall.  I managed to move the tables out and got the computers hooked up before my boys decided that they had enough fun in the classroom.

I love the idea of the tables (no missing work shoved in desks), but I'm not 100% sure how to set them up.  Right now I have three groups of two rectangle tables put together.  I'm not sure if I will keep it that way or not.... Decisions, decisions.

I would love any input or suggestions on the table situation (storage ideas for supplies as well - :) please and thank you!).

Also, since this is the first time that I will have my boys in my classroom before and after school, I would also love any suggestions for keeping them busy while I work.
