Greyzed Theme login in section

Hi
I am new to the wordpress land and have started to use the Greyzed theme which i reckon looks great!I am just wondering if there is a widget or an application that enables people to log in to my forum in the top right hand corner of my page. At the moment you have to open a thread and hover over “logged in” to open the log in page, can this be done?

Also my post page is my home page and I cant change the Order of the home page or rename it even by changing the front page in settings, How do I fix that. Please bear in mind that I do not have control of the host control panel.

Any help would be appreciated
