Using WordPress as a CMS

I’ve recently decided to take the plunge and utilize wordpress for my next website project. In this project wordpress will be used as a cms instead of for blogging purposes. I’ve read where you are able to do this but I have a couple of questions.

Can anyone recommend a resource that will show a step by step on how to transition from a photoshop layout to a wordpress theme?

In wordpress, am I able to have more than two templated layout pages? What I mean by that is I would have a home page layout, a secondary page layout and possibly a third. All of these would be based around the same theme but the content on each page would dictate which pages get used.

I also need to incorporate video into the website, what would be the ideal way to incorporate this into the overall site design (embedded swf, mov, something pointing to youtube) for ease of managing and playback? Is there a way to incorporate the video so that it is separate from the templates and is more or less flowed in with the rest of the content. This way if the owner of the site wants to delete one video and upload another they would be able to do this? I believe you can in a blog format, I’m just not quite sure when the site doesn’t have a blog and wordpress is used as the CMS if it would still be possible.

Any help would be greatly appreciated, I’m new to WordPress and I can’t wait to get started, but before I go down the road too far with WordPress for this web project I would like to know what’s possible.

Thank you in advance for any help that you may be able to offer. I’m looking forward to learning WordPress.
