Could you recommend me some plug-ins?

I sent venturemaker an email but there are a few other plug-ins that I need and was wondering if you could take a moment to recommend a few to me.

1) I'm looking for a picture gallery. One that will show up in a widget and when that particular picture is clicked on it will go to a post page with more info on what is in the picture. I have seen a few that I like But I dont want the end user to have to do too much to get it to work.

2) An embedded video plug-in that doesn't have to use the embed code from video sites.

Any help would be appreciated. Thank you!
