I understand your apprehension at trying to learn a new technology when you  
just want to get something simple done, but in this case I absolutely  
guarantee that if you want to get real audio work done with Linux, you are  
going to HAVE to use JACK. It is not an option. I would suggest you learn  
it now and get it out of the way.

I would also like to say that this sentence you wrote - "Card has input -  
program needs stream from card's input - hit a switch, make a patch, and/or  
turn up a fader and it should be a done deal" - almost exactly describes  
how JACK works.
