Some report that yes, for stability, it should be that way while others don't report the same findings. I personally see no difference in stability with things near the same or spread apart.
For instance, if my CPU/NB is 2700 and my HT is 2100, there is no difference in stability for me compared to 2700NB / 2400HT.
It's more important to know what each little piece is actually doing. The HT Link is providing a channel (link) to your PCI bus and other functions whereas the CPU/NB is the IMC (integrated memory controller) which handle the link between your CPU and RAM.
So, when you boost your CPU/NB frequency, you'll experience a 'snappier' feel to windows opening/closing/running programs and also you'll see a performance boost in benchmarks.
When you boost your HT Link speed, you're basically giving the PCI bus system more bandwidth to operate on. The problem there is that most card setups today won't need more than 2000Mhz on the HT Link (even a GTX480/ATI 5970) because it'll already have a hard time saturating that bandwidth. However with increased HT frequencies, you may notice an increase in synthetic benchmarks which is due to the frequency being higher.
