I've read the topics here in which the speakers had problems. How do we maintain our sound system in good shape? What are the main culprits in damaging the speakers?

Excessive moisture and direct sunlight are the two biggest problems for speakers, except of course over-driving them in some way. As long as you don't push 'em too hard they'll last decades provided you take care of them.
Also, don't store them in a position where the cone faces up or down. The cones can sag after several years, especially subwoofers.

When you over-drive a speaker, it usually starts sounding very distorted.
As for the cone-up or cone-down thing, I was mostly talking about storage. If you lay speakers on their backs (cones facing up) and store them for a few years, you may find the suspension has sagged over time.
I have seen some subwoofer cabinets designed to face the woofer down though. It's an interesting design, and makes the woofer cone "invisible." But the disadvantage is that the cone weight will tend to shift it downwards, which will only get worse over time.
The face down subwoofer storage sounds interesting. Do you mean to say that using the speaker is better than storing it because the dormancy will make the cones sag?
I've noticed several old speakers having their dust covers pushed-in. What may have caused this from happening? Does it even affect the speaker output quality when the dust covers were pushed-in?

Curious fingers are usually the cause of dented voice coil covers. Something or someone has pushed them in. They do contribute to the sound in most speakers, but not subwoofers. Subs usually have a cap that's harder to dent too.
Fortunately, it's usually an inexpensive and easy fix. Take your dented speakers to a speaker repair shop and they'll replace those dented caps.
Positioning a driver "face-up" or "face-down" can make the suspension sag over time, especially subwoofers with heavy cones and loose suspensions.
Will this happen to the subwoofer even when it is used regularly and used in a normal position? How about when it is used regularly and the positioning is not correct, what will happen to the subwoofer?

If the cone is "face down" then it will sag over time, even if used regularly. If the cone faces forward, the suspension will not sag and the driver will last much longer.
