I'm glad ASIO4ALL sorted it out for now--I was about to suggest it then noticed your edit.
As for your other problem, I personally find it useful to have a small, portable interface for some uses and a larger one that never leaves the studio but I "take the show on the road" quite often. In my case, I use an M Audio Mobile Pre mainly because it is fully USB bus powered meaning it's truly portable for location recording without needed to find a mains socket for my interface. Whether this is important to you, I can't know. However, the two interface solution works well for me.
