If your site is new and you have little content and visitors then it wont show in serps for some time, vbseo does nothing to get your ranking better, it simply enhances the way your links...etc look to people and search engines, vb4 is much better at SEO now than vb has ever been so i'd say you can do without vbseo.
The only way to get yourself seen in the serach engines is by working hard at your content, getting back links to your content from other sites and attracting visitors.
Sorry but there really isn't a shortcut
