General Support: Install Plogger on my localhost

Hi,
I am trying to install the gallery on mylocal host.
I am completely new to database & don't really get the installation.

What do i need to enter when ask for the DB connection?

1) I have created a database, but do i need any tables?
2) I do not have a password & wish to leave it blank
3) Is there any written example on how to enter the connection?

For example it says:
<?=$form['db_host']?>
When I enter my host name, shall it bw
<?=$form['db_http://locahost/me']?>
or
<?=$form['localhost/me']?>

What will be the gallery name?
<?=$form['gallery_name']?>

Thanks for your help
