I'm with Bill on this one. It's almost not worth the time trying to fix those problems and just beat on the Lumina until it breaks something big. Then find another daily driver.
My buddy has that motor in an oldsmobile (forget what model it is) and it's always been a PITA. Like right now, it barely made it through high school with him putting at least $50-100 in repairs ever couple months. For the past few years it's been sitting because the engine started to act up. I was going to buy it and beat on it but even I couldn't figure out which sensor(s) were bad and I had it hooked up to Diacom .
As for the vibration, that's the 1st major harmonic if it's violent and then goes away with higher speed. The axles are unbalanced BIG time if it's vibrating bad on a FWD vehicle! Probably a bend axle from improper length or weird suspension geometry (hitting a curb could bend it).
For $1000, I'd hold off for the time being just because of those 2 major issues. Doesn't help that it's fwd, missing 2 cylinders, and no power adder . That's just my opinion. If you plan on keeping the car for a long time as a DD and want to install a 5-spd then it might very well be a good deal. The ticking would worry me enough to crack open the valve covers and look at the buckets. Sounds like a shim is gone or a cam has worn it's bearings in the head (pulls the cam off the buckets so it ticks).
