Help? Configuring "index.php"

[stealthpaws]

I am NOT code writer, which is why I was searching for a simple gallery program.  That being said, I have searched every piece of documentation I can find to try to find out how to do some very simple things on the index page.  1:  I'd like only one row of thumbnails in the Random Files and Last Additions sections...actually, I could do without the Random entirely.
2.  There is a file called anycontent.php.  I assume it has to be called from the index page.  It says I can enable that from "Admin".  I'll be broiled and burned if I can find anything anywhere to turn that "on", and it isn't present in my page.  Please be patient with my lack of knowledge- I've searched this site, and all the documentation for the past 7 hours or so trying NOT to come here and look stupid...but oh well.  Here I am.   My page is http://www.stealthpaws.com/coppermine/index.php.
Thank you.
