The example schema and solrconfig are intended to show you a large number of possibilities, they are not necessarily intended to be "best practices". I would argue that if you do _not_ want to have dynamic fields defined, you should take them all out. And you should take all of the other field definitions out that you don't want in your specific installation. Ditto with the solrconfig stuff. Do you use QueryElevationComponent? Clustering? Autosuggest? No? Then rip them out. Ditto with unused field types. Ditto with....
I admit this is a personal preference, but the next person to try to maintain your system will thank you for not having to wonder if s/he needs all that stuff. HOWEVER!!!! Do not remove _version_, _root_ or "id" fields from your schema.xml file unless you're absolutely certain you know the consequences. And given your first question, at this stage I suspect you don't know those consequences ;). The same for any schema.xml field that starts and ends with an underscore (_)... And watch out for the "text" field. If you remove it blindly, your schema, the core won't initialize since the solrconfig.xml file look for the "text" field in several handlers to define the default search field if no field is explicitly placed in the search. This is not hard to fix, just be prepared to spend some time chasing stuff like that down if you aggressively clean up stuff you don't think you need.
