Parts 12/15 are the metal retainer. Parts 7/9 are what you are looking for. Get parts 22 (8) and 34 (2) for both sides, unless yours are still good.
The rubber weatherstrips will come off without removing the metal retainers. As mentioned above ^^^^ take care not to tear the new molding.
As far as I know the moldings do not require adhesive.
While you're at it you might check to see if your upper windshield molding is shrunk or in bad shape and replace that at the same time. I just replaced my '94 windshield molding and it looks awesome. For the windshield molding the metal retainers do need to come off, it's a little more work but IMO it's worth it.
