CODE

<!-- begin code provided by createblog.com -->

table.footer, .mainleft, hr,  table.footer, table.navigation, table.search, #SearchBar1_pnlYouAreHere {
display: none;
}

<!-- end code provided by createblog.com -->

..there i organized it.. you could actually put all those classes together 'cause they're all "display:none;".. which means they won't be visible.
footer= the footer
footernav=footer nav (redundant)
mainleft= left modules
hr= that trim line after all your entries
navigation=top navigation
search and #SearchBar1_pnlYouAreHere=searchbar
