The CT blower will not change the realiability of your car. With the exception of changing a blower belt every couple of years, it will be exactly the same service schedule, exactly the same realiablity, but with more hp.
The shift points should also remain the same. The power curve changes shape a little bit, but for the most part, it just looks like you lifted the curve on the dyno chart. This is especially true when you get past VTEC engagement, where spirited driving takes place. You may run through clutches and brakes faster if you track the car a lot, but that is due to adding hp, not the blower itself.
Drivability improves noticably, as you know actually have some low-end torque.
Here is an old dyno chart from when I had a 3.0L CT blower motor:
