In the US, they are still valid for postage at their face value. The US has never de-valued their postage stamps. For a collector's value, you would have to consult a catalog to identify and value the stamp. Look for one at your library or on line.
These are still quite common whether you mean the 20 cent regular issue or the commemorative which was issued soon after he dies. Its retail value in good condition - no missing perforations or thin spots and full gum if unused and lightly canceled if used -- is from 10 to 20 cents retail. Dealer would charge up to twice face for the mint stamps. Wholesale, the value is 50 cents to 75 cents in lots of 100 for the used commemorate and 15 cents per hundred for the 20 cent regular issue. Unused about 65% of face if you have enough unused stamps to make it worth a dealer's time. Full sheets and plate number blocks can often be sold for full face and maybe 20% more.
These stamps are listed in Scott as numbers 528-31. If they are unused and unhinged, their catalogue value is $1.85 (2008 value). Retail value is around $1.00 at most for the full set. I have attached a link to a set selling on StampWants
Not necessarily. Many stamps are valued for their cancellations and sometimes the envelopes they are "tied" to.
Sample Scott Numbers C40, C45 and C47. While most airmail stamps tend to be worth a bit more then regular issue stamps these are the most common and are valued at 15 or 20 cents mint or used, the minimum amount required to catalog and stock the stamps. Unused will always be worth at least their face value. Special cancellations and different values are likely to be worth more. Consult a postage stamp catalog, usually available at your local library for exact identification and catalog values.
The value of your 40 Elvis 1992 29-cent postage stamps largely depends on their condition and whether they are used or unused. Typically, these stamps can be worth around 20 to 50 cents each when sold individually, so your collection could be valued between $8 and $20 in total. However, if they are in pristine condition or part of a special collection, their value might be higher. It's best to consult a stamp dealer or an online marketplace for a more accurate assessment.

Not yet, people still do it. At one point it was the most popular hobby in the world. It has died off with the reduction in useage of mail as a primary communications mechanism. Older stamps are getting harder to find and more rare and the cost is climbing.
