Looking for a couple of plugins/functionality

Hi all,

I’m looking for a few plugins, and am wondering if anyone knows anything off the top of their heads.

1. I need a basic image viewer that has one large image with, for example, 3 small thumbnails below it. When a user clicks on a thumbnail, the top image is replaced with what was in the small image.

2. I’d like to have a “view more” similar to flickr, where the prev / next buttons are a specific image for the previous and next posts.

3. I’m looking to have my homepage be one huge featured post, with a large image, following by three side-by-side “semi” featured posts below the main post. I’d like all other recent posts to appear in the sidebar as linkable images.

I’ve done quite a bit of searching in the plugins and forums, but haven’t turned up anything like what I’m looking for.

Any help would be greatly appreciated.

Thanks
