Removing Breadcrumbs & Announcement/Postings Title

[Blue!]

I am using a bridged version and do not want the breadcrumbs to display, can this be done in admin? If not where do I go in the template to disable it?

Also, how do I remove the section markers for Announcements / Postings (defined in catbg3)

Can anyone point me to what kind of thing I am looking for in a template to delete the breadcrumbs, I have looked but couldn't find it...

Basically, I just want to hide the headers for announcements and postings, as highlighted in red here:


And to remove the breadcrumbs, I am pretty sure this can't be done in the CSS (either of them) but I have looked in the other files and I couldn't find where to change this...
