Compiling a Compact 256 Turbo partslist

[Shockwav3]

Hi there,
I'm currently in the process of gathering parts for my Compact 256 Turbo PCB and have a few questions left

1.) What's the value of the coil? 10mH? 100mH?
2.) What's a suitable Zener Diode for the 12V supply? Would a 13V variant work?
3.) I'm having some issues reading the values for the ceramic capacitors on the board Here's a list of what I found and how I interpret them, would be cool if one of you could doublecheck them:
m15 = 150nF
n20 (near the 14MHz crystal) = 200pF
68p = 68pF
n39 = 390pF
6n8 = 6.8nF
20n = 20nF
10n = 10nF
