Is it worthwhile to get my own full genome done (since it’s only around $2000 these days)?

Hello, I did an African mtDNA ancestry test in hopes of pinpointing a tribe of my African lineage (that's what the company claimed they do). I'm an African-American woman. I received my results and it said that my lineage was of European descent, non-African. What does this mean? I was very confused because I'm clearly black as are my parents and grandparents before them. Does that mean there is no African in me at all or that they just didn't find it?

I was reading about how they used DNA to identify the body of Richard III in England. How could they use 600 year old DNA to identify him?

I have heard that a paternity test would have trouble telling a brother/sister relationship from a mother/son one. Is that true? If so, why is that? And are there any tests that could tell the two apart?

About how far back can a standard genetic test trace family lineage and how accurate will the results be the further back they go? How good are they at telling how related two people are?

My extended family just had 23andMe testing and a younger brother and older sister found out they probably aren't brother and sister. They are OK with this but we are trying to figure out how they are related. The results show they are 25% related except on the X chromosome where they share no DNA. Most likely given what we know about our family's history they are half brother and sister. Can you tell from this information if they share a mom or dad?
