  Worn drums and pads will cause you to need to pump the pedal 
once or twice to get brakes.  There really isn't an "operating range" 
on the wheel cylinders unless you get out so far they blow the 
seals clear out.  Odd to have a new one leak, you probably flushed 
the fluid when you changed it.  Your rear braking will be severly 
diminished with flui on the shoes.  Would be a good idea to put in 
new cylinders, shoes and fluid and see what that does for you.  
Sounds like new bearings and seal would be good at least on the 
one side!  Wobble even with the nut tight soulnds like a bad 
bearing and that could be your noise.  Jacking up and spinning 
the wheel MIGHT give you a clue.  Not like you can spin it very 
fast though.  
  The other things that can make a rear noise would be exhaust 
related.  You can tell that simply by making the noise, letting off 
the pedal and pushing in the clutch.  If the noise persists then it's 
not exhaust.  If it goes away then consider a bad muffler, another 
hole, bad hanger or something bent and rubbing.  Not likely it's 
a frequency droning since it didn't do it before.  Dad's Passat has 
a droning at about 75mph that lasts for about a 3mph range.  That 
one's exhaust "tuning".
