rwilliams Hi
1) Increase logo size: Try add this to custom.css file :
.logo-image .logo-img{max-height:100% !important;}
2) Also what I want to do is have the menu item: Agencies & Subsidiaries, remain the same size although it has a sub-menu.
Try change the earlier CSS suggested to:
.navbar-default .navbar-nav > li > a,.nav > li > .separator{font-size: 18px !important;}
and change font-size value accordingly
3) I was unable to get the menu side increased
Try add this also to custom.css file :
.t3-mainnav .t3-navbar{margin-right:0 !important;}
