Using and editing AZ Index

Hiya,
I am using Suffusion –
I have recently installed the plugin AZ Index to display my posts in a list on a page. Fine, but just not sure how to edit it. The plugin is rather ld and there is not much help available it seems.
But, I can edit the CSS in the settings, just not sure what to do.
I wish to change the colour of the index’s displayed items.

Has anyone else had any experience with this plugin? Is a long shot but I thought I might ask here. Any help would be great.

Here is the Stylesheet for ungrouped index items:
.azindex .head {}
.azindex .subhead {}
.azindex .desc {float:left; font-size:80%; padding-left:10px;}
.azindex {padding:20px 0 20px 0}
.azindex h2 { color:#000000; padding-top:0;margin-top:0}
.azindex h2 .azcont {font-size:50%;font-style:italic;}
.azindex ul {list-style:none; padding:0 5px 0 5px; margin:0;}
.azindex ul li {clear:both; padding-top:5px;}
.azindex ul li.azalt {float:left; width:100%; background-color:lightgrey;}
.azindex .spacer {height:20px;}
.azlinks {text-align:center;}
.azlinkspacer {height:20px;}
.azpagelinks {text-align:center;}

and…the Stylesheet for grouped index items: (not sure the difference between grouped and ungrouped)
.azindex .head {font-weight:bold}
.azindex .subhead {clear:left; float:left; padding-left:10px;}
.azindex .desc {clear:left; float:left; font-size:80%; padding-left:20px;}
.azindex .head .azcont {font-size:90%;font-style:italic;}
.azindex .subhead .azcont {font-size:90%;font-style:italic;}
.azindex {padding:20px 0 20px 0}
.azindex h2 { padding-top:0;margin-top:0}
.azindex h2 .azcont {font-size:50%;font-style:italic;}
.azindex ul {list-style:none; padding:0 5px 0 5px; margin:0;}
.azindex ul li {clear:both; padding-top:5px;}
.azindex ul li.azalt {float:left; width:100%; background-color:lightgrey;}
.azindex .spacer {height:20px;}
.azlinks {text-align:center;}
.azlinkspacer {height:20px;}
.azpagelinks {text-align:center;}

I have tried editing various things..to no avail however.

Here is the contents page I need to change:

Also – some of my post titles are a different colour. Not sure why! This is because the titles are hyperlinks. Some are not , and I dont know how to change them all to one or the other!

Thanks !!
