1. Create 2 menus – 1 for logged out, one for logged in
2. Modify header.php and display each menu depending on user login
find menu and replace with:

if (is_user_logged_in()) :
//use the logged in menu
else :
//use the logged out menu
endif;

Thanks!

And in the menu page add the above page links to your menu.

I use this 4 my website penpencilreview .com(U can just visit it to find it since you are logged out).

And you can redirect the the login link to your customized page(TML login page) from the setting box. Hope it helps.
