You probably have a Presta valve. Go to a bike shop and get an adapter (for about a buck and a half) it screws on that valve and then you have a regular valve to inflate

Many possibilities, including derailleur outer limit not correctly adjusted, derailleur not mounted correctly, tight bend or friction in cable. Talk to the store manager/owner about correcting your complaints or find another shop or a bike co-op. If the bike is a major brand from a bike shop (Trek, Giant, Cannondale, etc.) try going to their website, look for Customer Service/Support and enter a complaint.

Getting Riser Bars or simply flipping the stem over or getting one with a different rise and reach might give you the added height you need. If you LIKE the handlebars, the stem is the best and least-invasive option as most new ones come with front loaders (detachable front caps) that allow replacement without stripping components off one side of the handlebar. In minutes a Bicycle Shop could swap any number of them onto your bike for you to try.

If the model is not right on the frame the bike has been repainted, which lowers its value. Year is not very important. Serial numbers are not very helpful, but you can try Google search for "Diamondback serial number". Also, see my tip: How to determine the year value etc of your bicycle

The front bearings on this bike seems to be quite standard, but there is a choice between steel and aluminum or stronger bearing cones. Any bike workshop should stock them and replace in little time at such low price, it's not worth wasting time trying to do it oneself.

Bicycle manufacturers generally only print one "owners manual" version that covers all of their bikes. They are very generic in nature. If you are looking for a resource on how to fix your bike, your local library will have millions bicycle repair manuals, Amazon, Half.com and YouTube are great resources.

Sounds like it is a chain guard. Chain guards are cosmetic to a bicycle and do not affect the functionality of a bicycle being operational. You will probably be just fine without it. In fact, you never see a bike used for racing with a chain guard, it's just extra weight to haul around.

Underneath the seat is an adjustment. It is right underneath the seat and has notches in it..
