The EV icons (restore, delete, archive, etc) that are visible in OWA depend on how you've configured your mailbox policy. The settings are located in mailbox policy - Advanced tab - OWA 2003 in the drop down menu. As for how EV search and Archive Explorer are displayed...I don't believe you have a choice as to where these options are situated. Looks like you can either make them visible or not and EV will automatically places them on the lower lefthand side and not on the toolbar on top just like your screenshot.
