Hi,
Commonly, phpmyadmin is installed in the DocumentRoot of apache, so, if you're using apache as you http server, you can access to phpmyadmin from the browser using one of this address:
http://localhost/phpmyadmin
http://localhost/PhpMyAdmin
Of course, if you've configured a different host (let's say that you system host is ajeetraina.net) then you should change the address to match your host (for instance
http://ajeetraina.net/phpmyadmin)
About options to config, you can check the
main documentation from phpmyadmin's page, or you can check out the
official wiki, or even you can check several howto in
howtofroge.com.
Regards
