8.1 is no issue. Working with that since it was out. Cross works with 8 for almost 2 years (even older version do).
In asio4all, one of right bottom buttons opens more of the asio features. You can select channels of mulitple cards (if you have). Always select what you need only as it takes performance.
It is a little hard to tell from a distance. Soundcards can be very different in behaviour/features. Some have one channel, other many, Some can be enable individual, others are paired.
Generally the more expensive the more detailed options.
Also hardware can have options, like front and back audio split or linked.
If you have internal and external soundcard, you likely can use both in ASIO4all and by that have your dual stereo setup.
