Its called smurf tube - flexible pastic conduit and gives some measure of being technology proof in that you can pull out the old tech and pull in the new. That said I've seen lots of house with many 100's of $ buried in the wall that never get used.
Put speakers in the ceiling instead of the wall - its more resistant to furniture re-arrangement even though it gives a slightly less prefect audio image. Mostly when you've got these spkrs on though you just want multi-media drama, not audiophile sound. A ceiling speaker in the dining room beats the doo-doo out of hearing your super speakers from the next room.
Definitely have a pro install the central vacuum piping. It costs only $200-300 for the house (you can choose to add the vacuum itself later on).
Phone jacks are over-rated - a good example of how cordless technology has rendered much wiring obsolete, and no reason to expect this won't continue.
