Ah I see, are you getting lots of features because of the business line? If not most cable companies offer connections with uploads equal to that or greater and downloads much faster.
The Multi Router Traffic Grapher (MRTG) is a tool to monitor the traffic load on network links.

There are tons of knowlagable people on this site, and whereever you buy it from will have some type of customer support that you can talk to. If you can find place where you can pick it up locally I would do that because they can give you an idea of what you have to do and they can guide you on the installation. If not you can find help elsewhere if you need it.
Yea they would reinstall windows, but you would lose all of your files so make sure you back up everything you want to keep. (music, word docs, excel, pictures)
I had a computer that had all of the bundled stuff installed with windows which had many problems, random restarts, and trouble booting up. I was going to return it but I first reinstalled windows with a clean disk without the manufacture bundles and haven't had any problems since. I would recommend you do this is if you cant find anything else that will fix it.
