It probably means that you don't have any images in your filmstrip.
Or in the Lightroom Toolbar you have Use: ____ set to "Flagged Photos" and none of your photos are flagged, or you have it set to "Selected Photos" and none of the photos are selected

be sure you're clicking inside the thumbnail when you want to drag pictures, not just on the frame around the thumbnail. It's not a preference setting, it's just the way Lightroom works

Use the Template Browser to save a template of your work.
Also, use the Save Web Gallery button at the top right of the preview area.

LR 4 (the current release is 4.2) handles collections differently than LR3, which stores your web settings in the collection. LR 4 does not, it saves them in saved web galleries. So be sure to create templates i LR3 of every single gallery, autoindex, stage, Pages, or whatever else you have. When you upgrade to LR4, your templates should all be there and you can apply them to the collections holding your galleries and then save them as Web Galleries in the Web Module.

Other than that, just the standard backing up of stuff.

Open your FTP program. Connect to your web server using the credentials supplied by your host. Each FTP program is different so you'll have to read the documentation for yours to see how to enter your FTP address, username, and password.
Once connected to your server space make sure to navigate to the root of your site (usually the public_html folder). this is often done on the right hand side of the interface.
On the other side of the interface navigate to the location on your computer where you've placed your TTG export.
Highlight the files and click the upload button or whatever your FTP program uses

And since you'll probably come up with more questions along the way, be sure to visit the FAQ in the Announcements and Information section right at the top of the forum.
And this blog post on my site might help as well.

Matt recommends Bluehost: http://wiki.theturninggate.net/doku.php?id=bluehost

I switched to them a few months ago and have been very pleased. Their control panel makes it easy to find what you need, to create subdomains, to redirect urls, etc.
And all the ttg things work just fine.

Looks like a server problem. Looking at the results of the autoindex verification it shows a php realpath() failure:

Post a link to your site

hmm. I noticed earlier that you could see the text: &midot; in your menu. The color of the font was different, it was a lot darker.
Try highlighting the area in the browser around the menu items. You'll see the dot show up. It's small, but it's there. You might need to do a search to investigate what kind of css or other php coding you might need to get what you want.
I'm not up on that stuff and Matt is gone for a few days.

As the documentation states,
"To get the server path, upload published content containing a /phplugins/ folder to your web server, then ping the path.php file in your web-browser at that address. For example: http://www.yourdomain.com/phplugins/path.php"

What this means is that you need to enable phplugins (Site Info> PHPlugins), export, and upload the contents of the exported folder to the root of your site. In your case, you don't have Pages yet so you've uploaded the phplugins/ folder to the folder you've indicated. Then you enter the url shown, (modified with your domain name/folder_location) and the result in the browser page is your server path.

Enter that server path in the "Server Path to PHPlugins without trailing slash" window.
