Help with radio buttons

I need some general help with radio buttons. Here is what I want to do:

I need two radio buttons which correspond to a tinyint column in the DB. I want the radio buttons to be pre-selected to the DB value. When a user changes the selection, I want the changes reflected in the DB without clicking on any buttons.

I have found in_place_control plugin but can't figure out how to use it/install it. I can create the buttons - but they are not pre-selected and I am not sure how to do the update.

Help is much appreciated - code examples are great. I have the books and have read the api - so if that is your advice don't bother.

If you use the check_box helper, the default value (set in the database itself) should be selected on new records, and the actual value if it's an existing record.

OK - but when a user makes a selection I want the value reflected in the DB with out forcing the user to then click a button. I have read up on observe field - but my understanding is that it does not work with radio buttons. Any suggestions?

Thanks, K

Add on 'onClick' helper that fires off a remote_function call that updates the database.
