Blue and green screen are used to produce a chroma key which is a matte for video.
Mattes are one method of controlling transparency in video. Another method is masking or rotoscoping the video.
Think of transparency as a window through which you can see whatever image/video (or portion of an image or video) you wish to place there.
Green screen is used during production or shooting the video, chroma keying (of keying for short) is used in post production.
In other words you want to isolate a portion of your video and therefor you shoot it against a green screen to apply a chroma key in post production and remove the green to make a matte for the footage.

The image of the woman is being used as a matte for the other footage. You need to research mattes. Both After Effects and Final Cut can use mattes.
Search the tutorials here and on the web. Here is one that may help you understand the technique:

I’d recommend against it. The Core 2 Duo is not really up to the task. You’d be better off buying a refurbished machine directly from Apple.
If you’re dead set on a laptop, look for an i7, they’re quad core and you can get one for around $1000.

Its not clear to me what’s going on, the render settings and the timeline look OK. I’ve opened the aep file and don’t see anything amiss.
If its only type layers from Photoshop that aren’t rendering you might try to convert these to editable text and see whether this makes a difference.
I suggest you make duplicate of the Comp and then convert the layers to editable text.
