Answer 1 - just follow the explanation in "config_local.php"

For 1 library:

$config['calibre_directory'] = './Calibre_library/';

for multiple libraries:

$config['calibre_directory'] = array (
     "First database name" => "./Calibre_library1/",
     "Second database name" => "/Calibre_library2/");

Answer 2 - Edit (with a text editor not a word processor) the file (in the COPS directory ./templates/default/styles/style-base.css
You need to change a few lines: (starting around line 219)

.books .cover {
    float:left;
    margin: 4px 10px 4px 4px;
    width: 60px; 
    height: 82px;
}

then change 60 and 82 to a larger number for example 120 & 164.

then you need to change one more line: (starting around line 214)

.books {
    clear: both;
   min-height: 90px;
}

change value 90 to for example 180. This value needs to be larger than the new value for height you just changed.

This worked for me.

Success!
