Not sure what you mean about there is no EQ2 button. There is. it just invis's when you dont need it. Simply hover over it and it will illuminate. Now, you probably dont know where it is to even find it...
If you look at the photo contained in this link

in the bottom right hand corner, just above the maintained window, you will see (you will have to look hard cause its dimmed out) the control center. Hover over it, and it will brighten up and there is your eq2 button along with a wealth of other important buttons.
Just so you dont have to look too hard. That control center is configured in a 3x3 arrangement (like a tic-tac-toe board). The eq2 button is in the lowest right position.
As for your other issue, check your chat window settings. You have the chat bar turned off. I cant recall which it is, but you will have to toggle a setting back and forth and the line to enter chat will miraculously appear (I think its the frame and title bar setting). However, this topic has been covered numerous times. Search is your friend
