To chain setup files you'll have to write a program that runs them one after another. The bootstrap manifest generator might be useful if you can get it to treat those other aspps like prerequisites that need installing before your setup.
Setups that offer Typical, Full, etc use these settings to derive a list of features that are installed. VS setups don't do features, so all you can use is conditions based on checkboxes, but there's no support for going back to reselect what to install later from Add/Remove Programs.VS setups aren't fully featured in that respect.
