Welcome to the community!
I'll answer what I can, but this is all from memory, I'm not at my box right
now. So beware.

I focus a terminal which would cover it.
In the rules table, add a[nother] entry for mplayer (or stick "ontop = true"
into the existing entry's properties table)
{ rule = { class = "MPlayer" }, properties = { ontop = true } }
I'm not sure about how to centre something though. I've bodged my rules.lua
(/usr/local/share/awesome/lib/awful/, I think) to allow a "centred"
property.

Claws-Mail or FF's Downloads) float

Window fullscreened.
Have one rule for your class (applies to all windows) and one for an
instance (a single window instance of a window class)
{ rule = { class = "Firefox" }, properties = { floating = true
} },
{ rule = { instance = "Navigator" }, properties = { floating = false}
},
The first rule sets _any_ Firefox window class to floating, then the second
one is applied to the main window only, and de-floats it, since only the
main window's class in "Navigator".
(Rule order matters)
You might want to check that the main window's instance is "Navigator" using
xprop, since I use swiftweasel instead of firefox.
Sorry I couldn't help with anything else. I have FreeBSD installed, but I
haven't done much with it yet.
