The name is not as important as it used to be. Yahoo SE does give you a few points for the relevant name but not enough to worry about.
FTVGirls.com does awesome and FTV did not really mean much when he started. First Time Videos. Now it means a lot.
The first thing to do, is get your site built and also get your content stream. Weather you will shoot it yourself or buy it. Make sure you have a back log of it incase of some low money days.
Then do some Basic SEO work on the sites. ( Hit me on ICQ to talk about that ).
Then think over an affiliate program. Keep in mind that you may never become one of the big programs, but you might. Make the program, and start slow. Look for new people to promote you. You may get lucky, and get a new guy that it just clicks for and all of a sudden he is sending 10 sales a day.
Now that you have some income flowing from the site, start to skim about 10 to 15 % as profit, and put the rest back into the site. ( time to talk with me about getting the REAL SEO work )
If I can help you with anything, let me know. My ICQ is in my sig.
