Slightly, but only the web pages you view the most have a lot of images on them. Otherwise, you won't notice much difference at all.

It will probably make some difference, but it probably won't be noticeable unless you look at alot of different pages with alot of pictures. The pictures on the pages you always look at will usually stay cached. If you happen to live in Portland, Oregon you can get fast cheap wireless anywhere in the metro are with Clear, and its pretty cheap. They say they are expanding to other cities soon too.

The best way is to disable other programs that are using your internet, and hunt constantly for malware, adware, viruses, and cookies and eliminate them.

A little, but you won't notice that much.
