There is no one true correct way of doing anything within the limited 
vocabulary offered by HTML. Whether something is an H1 or H2 will matter 
to search engines, but it's only one of many "ingredients" that will 
influence a page's ranking and indexing.

Presentation may affect *subjective* interpretation, but meaning should 
not be imparted solely via styling. A document needs to be 
understandable without styles.

This goes outside of the www-style list...the www-html list may be a 
more appropriate forum for this. Suffice to say: HTML offers a very 
limited set of elements. Beyond microformats or similar attempts at 
cramming further semantics into the very generic elements, or using 
linked resources (such as RDF files, for instance), there's not much you 
can do - and even there, you're relying on search engines actually 
caring about any of those things. As an aside, I remember how at some 
point MAP was touted as being a good markup structure for navigation etc...
You may want to look at the proposed developments in XHTML 2.0 
(specifically the "role" attribute and navigation list element)
