Both of these are excellent. Even if you don't want to follow these programs exactly at least grab Rippetoe's book "Starting Strength" (3rd edition). It is a great reference for all the big lifts - very well illustrated with detailed explanations. Getting stronger (especially as you get older) is critical to good quality of life.
Once you have hit your limits on those two programs move to Wendler's 5/3/1 :) I've done SS and now 5/3/1 for the last 4-5 years and I'm the strongest I've been in my life in my early 40s!
EDIT: Also another great thing about Starting Strength or Stronglifts 5x5 is that it doesn't require much of a time commitment. You can easily be in/out of the gym in an hour or less - if you are not goofing off, 40-45 minutes is pretty typical.
I just finished my second week of my first cycle of 531 Triumvirate + FSL and I'm loving it. In the next week or two I'll probably start tacking on some conditioning(prowler/ropes/kettlebells) after cause I still feel pretty good.
