Yes, they do, except for the Army Combat Uniform, which does not have epaulets.
There are a bunch of them. Branch of Service insignia, rank insignia and other insignia that aren't unit-specific are found in Army Regulation 670-1, which is downloadable from a few places. Distinguished Unit Insignia, which everyone calls unit crests, and patches are not in that reg; check the Institute of Heraldry website at http://www.tioh.hqda.pentagon.mil/
The Continental Army needed experienced professional military officers.
Yes. The Continental Army attacked commanding officers of the British Army. Because they were cool like that.

Army officers have to buy their own uniforms because they make more money than enlisted soldiers, who do not but their own uniforms.
Depends on your rank and the uniform. On the Class A uniform and dress blues, enlisted personnel wear fabric insignia on the sleeves, whereas officers wear pin-on insignia on the epaulets. On the Class B uniform, Private (E2), Private First Class (E3), and Specialist (E4) would wear metallic insignia pinned through the collar, whereas Corporal and higher would wear shoulder boards on the epaulets. On the older Battle Dress Uniforms (BDUs) and Desert Combat Uniform (DCU), rank insignia would be worn on the collar points. On the current Army Combat Uniform (ACU), it is worn on a velcro tab on the front of the uniform. Officers and Warrant Officers wear their rank insignia on the beret, whereas enlisted personnel wear their regimental crest. Rank insignia is usually sewn onto helmet covers - however, this is often a moot point, as the placement of the rank insignia on the kevlar helmet often leaves it covered by the mounting plates for night vision goggles.

That would depend on which Army or Air Force the unit was. -In a flying unit of a modern Air force there would be many officers as aircrew. In an Infantry unit there may be only a small percentage of officers.
