Always use the simplest and most productive workouts that you can to make the most progress in adding weight to the bar. As your strength and conditioning improve, it becomes ever harder to continue to make progress. Eventually, you'll get to a stage where you'll be planning entire two and three month periods just to add a couple of kilos to a lift and view it as good progress.
If you can make good progress with the Rippetoe program then run it until it stops working for you. You'll then need something a little more structured, such as the Madcow Intermediate 5x5, where you'll aim to progress week by week rather than session by session. You should be able to use the Intermediate, adjusting and reseting in various ways, for a good many months.
Eventually, even weekly gains just don't happen any more and you need to plan your programming in ever greater blocks of time and the Dual Factor (Advanced) version is needed. You'll then be looking at month-long loading phases followed by recovery phases and be measuring progress in months at a time.
Always take the simplest option that still works for you. After a layoff, you might even find that you can go right back to the Rippetoe for the first month of getting back into things, even after a few years of working out.
