I'm new to the world of bike riding.
The other day I bought a used Diamondback Crestview from a thrift shop.
I like the way it rides, but I don't know anything about the bike
itself.

It has the Shimano "twist" gear shifter.

What should the tire pressure be?
How can I determine the year it was made?
How can I determing it's size? (e.g. 26 inch? 28 inch? )
Is there a way to tell how much it's worth?

How high should I adjust the seat?
In other words, should I adjust the seat height so that it's higher
than my own bottom? (So that I have to stand on tip-toe when astride
the seat?)

Pop in to a friendly bike store. They will answer all your questions plus
help you with seat and any other neccessary adjustments.
I doubt if they would charge anything - although I believe some use computer
programs and may have a small charge for fitting adjustments. It's also a
good idea to get them to have a quick check before you start hurtling
downhills at breakneck speeds.

Thanks, Fred. Good advice. (Why didn't I think of that?)

Because - the main requirement for cycling is a total inability to think.

Usually the maximum is marked on the sidewall.

Probably impossible for many bikes -- some mfrs have serial number
schemes, most don't.

Frame size measurement has many variations -- usually it's from the
center of the crank spindle to the center of the top tube.

Usually with your leg fully extended, your heel should just reach the
pedal. That may make you "tip-toe" or not, depending on the frame design.
