Here you can find a list of many Linux equivalents for Windows applications. You might want to take a look at it.
About your drivers, if they are in *.tar.gz just extract them typing
$ tar -xvzf <name>.tar.gz
That will create a directory called <name>. If you type
$ cd <name>
Then you should find a README (or something that sounds like an install guide) ...
$ cat README | more
The instructions will appear there.
There should also be some documentation in the webpage where you downloaded your drivers. You should read them. They will help you a lot.
