Depends entirely on the chosen fonts and the size of your baseline. It's
not something I'd really want to try and explain, so try a search for
"baseline grid". FWIW, the first few results in Google look like useful
reading on this matter.
Essentially, the line-height should be equal to baseline/font-size,
which for a baseline of 2em, and a font size of 1.5em (say for H2
elements) the line-height would be 1.33333em. The margins would then be
either 1.33333em top and bottom, or you could move the margins around as
long as the top and bottom added up to 2.66666em (1.33333*2). It's a
little more complicated than that, but that's the basics.
I'm far from being a typography expert though, so I'd read up on it
anyway ;)

Indeed, which is why it depends on your font etc.

Yes, the top and bottom margins on block elements that usually contain
text, eg. P, UL, OL, H# etc.
I've found it helpful to use a "Reset" stylesheet that removes all
padding and margins etc from elements and causes all browsers to display
everything the same so you have a clear starting point for your own
styles. Of course, that means that paragraphs have no default margin and
STRONG/EM are by default regular text instead of bold/italicised, but it
does give you a nice blank canvas where you can predict things more easily.
