I just finished installing the IF buffer and noise reduction mods and have to say that I found the IF Buffer mod less "painfull" than the Noise reduction one.
Remove and replace one part; of which the most difficult thing was getting the new SMT resistor into position. Once there, I used a very small jewelers screwdriver to hold in place, put a little solder on the end of iron tip and then "spot soldered" one end; then I could solder the other end, finally going back to the other end and properly soldering it. I did not "cut" the SMT in half to remove it, found it very easy to use solder wick and then heat the resistor so it would slide off. The noise reduction mod took a lot more time getting the diodes and resistors trimmed, soldered, and into position. One thing to be aware of is the resistor is tied to the cathode of the diode for the components on the left side of the K3 and the resistor is tied to the anode of the diode for the components in the center mod.
