Will you use a low voltage enclosure, a wall mount rack, or a simple piece of plywood screwed to a few studs in a mechanical room?
There are a variety of options for patching phone lines (usually category cables), category cables for Ethernet, and audio (most people don't patch audio cables; the speaker cables are usually run straight to the amp or speaker selector box).
Patching adds a level of complexity that for some people isn't necessary; running category cables for ethernet, from each room, straight to the switch is common. A patch panel allows for easier changes to a configuration - not common in a residential setting.
Leviton, and many other manufacturers, have removed the complexity of 110 blocks for phone category cables in the mechanical room, and replaced them with simple modules/brackets. These devices can be easily snapped into the perforated back of a low voltage enclosure. Spend some time searching online, and visit the low voltage aisle of Home Depot or Lowes to see what's available.
