One thing in general I would also recommend is replacing the vacuum elements pre-emptively when you can. You have one in each of the doors, two in the trunk (one for the fuel lid). These are usually the problem with vacuum leaks and I have found it is often easier to just replace them especially when you are doing jobs around them (i.e. pulling the doors apart) than to spend the time later trying to track down exactly where the leak is.

The vacuum lines themselves rarely have problems and if you have something leaking under the hood, it is a lot easier to find where it is.
