Linux Distributions with Tiling Window Manager as Main WM

I have lots of experience using xmonad and I think you'll be fine if you give it a whirl. Regarding your specific questions:

• Almost everything will work just as they normally do. Regarding the specific list you gave, the only one that needs some TLC is chrome. Full screen is a bit flaky and you'll need to futz with your xmonad.hs config to get it to work properly but it's totally doable -- a little googling will turn up the proper changes to your config.

• You can find xmonad.hs files for dual screens here.

• Here's a link that gives you the details on installing xmonad using cabal.

• Xmonad is my favorite (tiling) window manager but I don't have much experience with the others but I hear RatPoison is pretty good.

The answer to your first question is: No.

But, there are window managers that can be configured to look and behave almost exactly like you want.

The answer to your second question is: Yes.

There are several window managers that are easy to use, without needing to configure them. However, what is percieved as "ease of use", varies from user to user and also depends on which system(s) they are used to before. If you're used to Windows 95, IceWM might work for you. If you're used to Windows XP, Gnome 2 or KDE might do the trick. It's also usually possible to "theme" windowmanagers and make them look like other systems. Some windowmanagers doesn't look anything like Windows, but are relatively easy to use, like BlackBox, OpenBox and PekWM. Good luck finding one that suits you.
