 * Recently I encountered the default PHP memory limit of my host (8MB), which I
   worked around by modifying my htaccess file. In order to reduce my load on the
   server I would like to determine what components of WordPress are responsible
   for the overload. Is there a profiling plug-in or utility? What are the memory
   usage implications of caching (wp-cache or similar)?

 * While I’m not aware of any profiling plugin for WP, I’m suspicious of your host
   having an 8MB memory limit. While this is indeed the webserver default, it’s 
   also likely to be a little “stingy” in a real production environment.
