I spent the five happiest years of my life in a morgue. As a forensic scientist in the Cleveland coroner’s office I analyzed gunshot residue on hands and clothing, hairs, fibers, paint, glass, DNA, blood and many other forms of trace evidence, as well as crime scenes. Now I'm a certified latent print examiner and CSI for a police department in Florida. I also write a series of forensic suspense novels, turning the day job into fiction. My books have been translated into six languages.
I'm afraid not. I'm guessing that would depend entirely on how large the bandage is and how much the person bled. Best of luck!
Yes, the arcsin of the width divided by the length of the stain will give you the angle of impact at which the blood struck the surface (usually a wall). The direction of the stains can be traced back to a point of convergence and from there the angles can be traced back to a distance from the wall, giving you the approximate point in space where the blow was struck.
Go to a college that offers a degree in forensic science. Each college or university should have a website where they list the degrees they provide.
It almost certainly would not be a deal-breaker. Just tell them the truth.

I would guess in his lap or to his right, but it's impossible to know for sure, since you cannot know exactly how the body was positioned or how powerful the load of the bullet might have been.

At it’s most basic, a trajectory is just geometry. If you can find two fixed points then you can draw a straight line between and beyond them.
