Quoted from mof:* Do I stick with stock flippers or upgrade to WPC-era flipper assemblies?
I found Stock flippers can be fine when rebuilt as well as per Clay's method of drilling several holes in the the metal bats to lighten - this made a big difference.
I feel flippers that are more powerful like the WPC style flippers may not really suit the game as they are way more powerful than what is needed.
Quoted from mof:* Am I trying out the magneto drops? Or will these old 1978 horseshoe switches be my friend?
Agree with Koji, Originals boards/wipers cleaned up or with new wipers (& lube) can be pretty good/reliable for some time, but further adjustments will be required. I found around 2 years problem free before needing adjustment.
Quoted from mof:* Where do I get the updated rom for with lane-change? How do I wire it up?
Details are here, but link to ROM no longer exists. I did try the ROM years ago but could not get it to work.

You can also get the nice original Star style transparent Blue guides here too if interested.
