Setting up X-Session for Ableton. Need help/ideas

I'm new with Ableton, and after watching Tom Cosm's video on DJing with it (as so many have), I decided to give it try. Unfortunately the only controllers I own are my X-Session Pro and a qwerty keyboard. Considering how many effect and EQ knobs I'm using (see the picture below), I only have enough for a single track (though deck should be a better name). My question is - how do I configure one set of knobs to control the same parameters but on different decks?
I know I can map on the keyboard switches to turn on and off the effects/EQ, but what I need to do is switch between decks without having to turn anything off, but at the same time only control one deck at a time (as in - if I turn the "low" knob, I want it to be just for deck B and not deck A&B at the same time).

Also have 8 available buttons and a fader on my controller - what would be the best way to utilize them?

I hope I didn't sound too confusing. English isn't my native language.
