You have a couple of options, but it involves a bit of work.
The first solution is to handcode the comps using only the types needed (this may not be an option if you don't have access to an IDE or are unfamiliar with the component API or C#). When you handcode, you have control of what to include/exclude unlike the generators.
The second solution depends on what type of generator you used. If you're using a web service generator, I suggest breaking out the web services you hit across multiple integration projects (assuming there are multiple web services). That way, you include only the types needed with each model/project. I forget if the web service generator has an option of excluding types like the Resource generator does, but that's an option as well if it can be done.
