Cache for the result of rendering a page. Rendering the wikitext is very intensive, thus it should be cached.

It refers to the interface messages. They are used all the time. It's a good idea to cache them.
== Question 2 ==
What are the benefits and draw backs with using either of the two options below, after excluding the other options?
- CACHE_DB
- CACHE_ACCEL - (eAccelerator in my case)
CACHE_DB uses the database, and thus performs worse than a specific cache accelerator. It may also produce db deadlocks.
CACHE_ACCEL seems a good solution for your case. If you had several servers, they would have independent caches, that's why memcached is preferred, but since it's on a single box, seems ok.
