In dire need of help with on-demand theme

I’ve been running my website on wordpress.com for some time now, but decided to buy hosting and installed wordpress on that. I’m trying to get my site up and running before transfering the domain name, but i’m running into a bunch of problems!

I’m using wordpress v 3.3.2 with the on demand 2.3.1 theme.

1 – I don’t understand that my carousel isn’t working. In the theme options, I don’t have it disabled, and I chose which category I want the carousel posts to be, but the carousel just doesn’t work on my site.

2 – How do I make it that all the posts I add show up on the home page as well as the category I put it in.

3 – my thumbnails aren’t showing up, but I think I may have to manually do that.

Basically, I want https://thunderpricescom.ipage.com/ to look like https://www.thunderprices.com
