I need to submit my website to directories, video sites, social bookmarking, ezine, press release and more

I own a Minnesota DJ Company. www.yourminnesotadj.com I am looking for more traffic to my site. So far I use Facebook, linkedIn, Myspace, Twitter X3, 4 blogger blogs, 4 wordpress blogs, social bookmarking, google local, Referring wedding sites, youtube and other video sites, direct mail and craigslist.

Do you think I am out of free media or is there more.
I also do some google adwords, facebook ads and myspace ads.

I recently had a bunch of recommendations by internet marketing gurus to take a look at a tool called Only Submitter. Here is what it is supposed to do:

Submit to:

Web Directories (755)
Article Directories (113)
Blog/RSS Directories (82)
Press Release Directories (15)
Video Sites (35)
Podcast Sites (87)
Social Bookmarking Sites (73)

It is a Firefox Plug in.

It is supposed to be customizable.

Here are my questions: Have any of you ever used it?

If you have used it, what do you think of it?

Has anyone ever heard of the guy whose name is on it? (Ross Goldberg)

Is it worth the asking price?

I have a video i made and i want to send it to all of the top video sites all at once from one site or page, is this possible? I have used only wire to submit to social bookmarking sites.
