Just as a note, the styles we release all make use of a seperate folder, not the images folder

. So when you upload the images, they need to be uploaded the your /styles folder (you'll need to create this, it is not a standard with vBulletin).
The /styles folder also needs to be in the forum root, so if your forum is in /forum, it should be /forum/styles/. If your forum resides in your website root, then /styles.
As for the additional menu, you can simply copy the current from the header and place it where you'd like

.
