Tweak SOBI2 - Joomla

We use sobi2 as an internal staff/worker database. We have had a filter tweaked in there (screendump 1) This filter makes sobi2 show only the workers who are connected to all the marked categories. 1: We would love to move this functioning to the frontend part of sobi2 so the filter/categories show in the top above the list of the workers matching the categories marked. We need this shown on frontend for admins only - like the sobi2 output page. 2: We need a search function so we can search for words written in the “Custom fields” (We have a field we call “Notes” and would love to be able to add “keywords” in our notes so we later can find all people with these keywords. 3: When a new worker has signed up via the online form: [login to view URL] we need him to be redirected to an article instead of log-in form since they don’t get to log in. And we need to give them further information after filling the form. We need these things done so that it does not comprimize the worker-database (We have previously had it crawled by Google leaving all the entries online - was not very cool ;). 4: We need the output page to show the entries a little different - in one line instead of two and showing: Name, Town, Email, Phone, Date of birth, Show if there are attachments. The reason for this is that some entries have 5-10 attachments and they mess up the overview a lot.
