Yes. Calling a template twice will only fetch the text once, won't increase the 'used templates' counter... Preprocessing of wikitext over a threshold is cached serialized (it's easier to reprocess if it's too small).
To clarify: there's an in-process cache, like Brion said, so a template that is used twice on the same page is only fetched and preprocessed once. However, this only applies to templates called with no parameters. If the template is passed parameters, this in-process cache won't be used, even if the same set of parameters is used twice.
I don't think so. The preprocess-to-tree is always the same, regardless of the parameters, and it is always used. It is the expansion where parameter change. I don't see that cache for parameterless templates, maybe it's the mTplExpandCache?
