Power Pro... are you sure it's for me?

Just ordered a 300yd spool of 50# Power Pro but still not convinced that
it's for me. However, I do feel that I may need it in Florida for the
Southern Classic, but for around here mono has fulfilled my needs.

Questions:

1. How different is this line going to be compared to Fireline?
2. Is it going to be noisy through the guides (like Fireline)?
3. Remind me of the black magic marker... I forgot why Rich says he uses it.
4. Do I need to modify my hookset? I've heard that some people have broken
rods with superlines.
5. Drag setting? Tighter, looser?
6. Not really a question, but a backing line is recommended, right?
7. Ok for fishing plastics?

Sorry about all the questions that I know's been answered here before, but I
tried to look back over the older posts but they've been deleted from my
server.

Thanks in advance.
