Installed WP on server, but blog not working

I hope this isn’t too long-winded…

I’ve created a website, http://www.neverbelateagain.com, and loaded WordPress files on my ISP’s server (1and1.com). I worked with three different techs at 1and1 to figure out where to put the WordPress folder/files (root directory? subdirectory? etc.). Now http://www.neverbelateagain.com is working but my blog is not. BTW, the techs have me using http://blog.neverbelateagain.com

While I have several websites, I’m focusing on http://www.neverbelateagain.com right now. I want to install the blog in a way that will help optimize search engine rankings (although I realize content is most important). My second priority is to do the same for http://www.50WaystoSaveOurAnimals.com.

To give you an idea of how things are set up, my FileZilla server side screen looks like this:

/
> dianadelonzor.com

> logs

> neverbelateagain.com
^ blog (this has the wordpress files in it)
^ public_html (this has the neverbelateagain files in it.
? aspnet_client
? docs
? images

> postmadison

> postmadisonmarketing

Also, under the Control Panel, Destinations, the 1and1 techs had me set things up the following way for neverbelateagain.com:

Current directory: /neverbelateagain.com/public_html

Home directory: Existing directory

Existing directory: /neverbelateagain.com/public_html

As I mentioned, I’m only concerned with setting things up to optimize search engine rankings for the http://www.neverbelateagain.com blog right now. My second priority is to do the same for http://www.50WaystoSaveOurAnimals.com. I’ve read that, to have the best search engine rankings for http://www.neverbelateagain.com, I should load the WordPress files on the root directory. But in doing so, I don’t know if this will screw things up when I start working on 50WaystoSaveOurAnimals.

I’m also interested in establishing a relationship with a person who can help strategize and implement the technical aspects of social media strategies. I am a marketing consultant and would like to begin offering social media to my clients. While I do want to accomplish this particular blog setup myself so that I’ll understand things, I don’t want to do this for clients – I’d rather hire someone.

Thanks!
