My focus is techno, and I own the 1k and find it useful..
also this guy I know does a tight live techno set and uses a 1k check out
www.mux.ca (i think its .ca).
however, using an mpc as your main soundsource isn't really the classic techno appoach: the classic techno feel is based off of a drummachine plus a stepsequenced analog synth, for instance roland tr909 plus tb303. It's the same way as hiphop cats say an mpc is classic for hiphop. both those roland machines are based around pattern sequences plus knobs you change to alter the analog synth parameters.
the mpc is good as the master sequencer for what you're doing.. and also use it almost like a recording device to keep sampling in different variations. but to make your setup more 'techno', you need to have some different pieces of gear, all playing back patterns at once, each gear having knobs you can tweak to vary the sound immediately in different ways. the microkorg is a good start and could be very 'techno' with the right adjustment. it could be good to supplement your sampled drumsounds with drums that are actually synthesized with knobby parameters:: korg er-1's are so cheap these days and could actually help you out a lot. or you could get more into software plus a midi knob/fader controller (not my preference though).
and yeah, the more f/x the better. it works well to get a mixer with multiple aux sends and put the f/x on that, so you can mix and match what feed goes thru what effect. since the mpc doesn't have many knobs, really working your mixer can make up for a lot of that.
just remember:: the mind set of techno is to work off a few basic sequence patterns, then create buildup and variation by changing the sound by knob tweaking. its a very handson vibe, really morphing and twisting up the sound until it screams.
