To go to chat, click this link. For the picture, you should see a button under your current avatar on your user page that says "Edit Avatar", so click it. I don't actually know why can't you edit, so I suggest you add '?action=edit' to the end of every URL of a page you want to edit; and I don't actually know what do you mean by "mail".

Hope this helps
