cannot limit posts in admin>reading

I am using the twenty ten child theme, and I cannot limit the amount of posts to my front page. When I set my reading front page post limits to 15 (my current setting), it lists my most current 15 posts in descending order, and then just keeps listing from my first post forward, so now I have 89ish on the front page. My site is adellaavenue.com. I have tried removing all of the plugins, I have no ftp access since I have wordpress through network solutions. The last suggestion I received on a previous thread was to post my index.php in pastebin, and perhaps someone can look through to see what they find, perhaps in the query portion. Here it is… http://lt.pastebin.com/FGcWDW4i I can really use some help with this. Thanks!
