Looking for good Flash reference books

Hey all,
So I’m a fairly new Flash App Dev (3 months) and I’m finding some of the… nuiances of the Flash API and it’s compiler a bit frustrating… Thanks to forums like this, I am finding solutions to the majority of my questions, and working around other stuff.

What I am looking for is solid reference books on the Flash compiler specifically, but also in depth reference books.

The kinds of questions I’d be looking for in these books…
Does Flash inline all constants? Most compilers do, so I would assume Flash does.
I understand that with CS5, all Flash and AS3 gets broken down into Flex… is it then run in a Flex runtime kind of like C# CLR?
(these are just examples)

I’d also be interested in the more popular design patterns in Flash… I haven’t done any google searching for it yet, so forgive me that, but I’ve found that Flash has some “different” paradigms like the whole “Export in frame 1” thing… So what set ups work best for Flash.

Anyhow, thanks ahead for the recomendations. And I’m not affraid to drop the necessary cash on solid reference material (or rather have work do it), so I’m not just looking for free reads onlne.
