Couple of comments and an answer I've
just c&p'd the relevant parts.

Update manager downloads all the features
on the site. It has to in order to do dependency checking. If your zip
is part of a feature jar archive then it will be downloaded when the features
are. The larger the feature is then the longer it will be before the user
will be able to interact with the UI. Minimizing the size of the feature
jar makes the browsing of the update site faster. The zip then only gets
downloaded when the install is triggered.

This much dependency checking/installation outside
of eclipse. You may want to reconsider using Update Manager as the primary
installation method. Sounds more like you need a native installer to do
this work for you. Update Manager is great for installation into eclipse
for features and plugins outside of that niche it isn't the best or easiest
way to install a product.

Have you looked at the tests and examples
in cvs and the development resources? 
Somewhere in here I recall seeing an
example install handler I think.
