Do preemies have difficulty breathing because lungs are tiny?

Surfactant. It has more to do with the development of the lungs. They are not developed enough to stay open and hold air/oxygen well enough. During late pregnancy the baby's body produces what is called surfactant and it helps the lungs expand and stay open with out collapsing so that air/oxygen can go through the lungs.
Often not developed. It is not size - often the lung tissue itself is not developed.

What could cause a spine to curve forward, leading to a compressed lung and causing difficulty breathing?

Kyphosis. Osteoporosis is the likely culprit. Brittle bones crack and fracture throwing the spine out of balance, resulting in increased pressure in an asymmetrical fashion, leading to more cracks and more bending in the same direction. Scoliosis is often also present. Chronic intake of certain medications such as steroids can cause or worsen the problem. Read more...

I was diagnosed with a partially collaped lung and pneumonia 2 months ago and still have chest pain and difficulty breathing, is this normal?

Possibly yes. I imagine the collapsed lung re-expanded to normal already but another episode of collapse may occur causing persistent symptoms. After an episode of pneumonia you can feel persistent symptoms of difficulty of breathing. If there is underlying asthma or cystic fibrosis then persistent symptoms may occur. Asthma and cystic fibrosis predispose to collapsed lungs and pneumonia. Read more...

If your difficulty breathing responds to asthma rescue inhalers, does that guarantee you don't have anxiety and you have a real lung disorder instead?

Not necessarily. I see you have belching, reflux, and now have experienced improved breathing with a rescue inhaler. The improvement with a rescue inhaler indicates you have reversible airway reactivity. This is not a disease of the lungs but, rather, a tendency of the muscles of the airways leading to your lungs to go into a spasm and possibly have inflammation. This can be on an allergic bases as in traditional asthma. In your situation the reflux may be causing small amounts of acid to seep into the airways making them more reactive. Food allergies can trigger increased reflux by causing esophageal inflammation. Having airway reactivity can cause anxiety and having anxiety can worsen airway reactivity as well as increase the severity of reflux. You will need to have the reflux addressed, determine if you have a problem with the ability of food to stay in your stomach and not come back up, see if your belching could be due to Helicobacter Pylori, for example, an infection that can be treated, and determine of you have chronic inflammation in your airways needing treatment.
