Drupal 6.x

I am trying to set up a website that will allow users to see nodes that are available but restrict access to view the body (and/or CCK fields). This way I can set up views to show a directory of "premium content" but restrict access to it unless they have a certain role.

Is there a way to achieve this?
Thanks

My new 6.1 installation is being hammmered by trackback requests. can I drop the watchdog table without further consequences?

I might be doing this wrong, but I believe when using the function:

drupal_set_message() i should be able to use the argument $repeat = FALSE to prevent messages from stacking.

This doesnt seem to be working.

The user flow is over two block modules. The messages are formatted like this:

First Block:
drupal_set_message($message = t('We have service in your area! Please fill out the trip information form below.'), $type = 'status', $repeat = FALSE);

I know this is probabaly related to the ongoing discussions on RDF

but is there are modules that give search features similar to the page below
particularly in the way it searches

We'd like to create a drupal based website that uses a flash page-flip

similar to http://miami.sixdegreesmag.com/
