You're probably fighting modern technology here. When computers started they went from text files to more elaborate types of file. With sound and graphical files we are talking major size. AVI BMP WAV and a load of others just sucked up disk space. This was one of the reasons compression software took off. Now, though, we have MP3 FLV JPEG GIF type files. These were created with inbuilt compression, or rather they were made to create files efficiently. Only the JPEG really give variable compression. The others will usually be approximately the same size as the original.
Sorry but you may have to get rid of some of the stuff you're not really into. The other option, of course, is to store the less used stuff on external media such as a USB stick, CD, DVD or external drive of some sort.

Yes, it's normal, but you can increase the compression level.
If you have Photoshop installed, there is easy way to reduce "weight" of image files: open picture and go to file -> save as and in the saving box move quality slider from 10 to 8, save picture and it would be few times "lighter" than before but the same pixel size and resolution.

Yes. Picture files do NOT compress as much as text files; as there is much more data in a picture file for it's size.

This is normal. I tried to compress down like a 100 MB video and it only shrunk by 2.0 MB or more. But this is normal.
