Well, you need to get your pre-keyed image/video into your video bar (not the timeline), and then select it (it should be outlined with yellow). Drag the pre-keyed thing into the timeline, onto the other video, where you want it to appear. Then, let go of it, and a little menue should appear. Select "Picture in a picture". Then you should be able to manipulate it (with size and area), and that's how it's done.
The Simplest Special Effects you can use are the ones built into iMovie. For Example, you can apply an instant replay function, or a video effect such a negative to a clip. To see other special effects that are more complicated like embedding a explosion into an iMovie Project, check out my Youtube iMovie Special Effects Playlist in the "related links" section below.

Yes, you can use Dropbox videos in iMovie. To do this, you need to download the video files from Dropbox to your device first. Once the files are saved locally, you can import them into iMovie for editing. Just ensure the video format is compatible with iMovie.
You speed the word as 'miskeyed'. When you put the prefix with the word keyed, you do not use the two 's' as when you say the word 'miss'.
You do need a camera to use iMovie. Import pictures and clips that are already on your computer/mac.
Yes, you can use iPhoto slideshows in iMovie by exporting the slideshow as a video file from iPhoto and then importing that video into iMovie. Simply create your slideshow in iPhoto, export it to your desired format, and then open iMovie to add the exported slideshow to your project. This allows you to incorporate your iPhoto slideshows into your iMovie edits seamlessly.
