Not quite. All those locations are policies do relate to drives but not in their mappings.
NoDrives
This one hides drive letters from listing in dialogs. Users could still map and use these drives, they just wouldn't see them. The value is a binary representation of the 26 letters of the alphabet, each bit representing a particular drive letter. On my Terminal Server, I use the following:
Hid drives 'ZYXW'
HKLM\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer
NoDrives REG_DWORD 3C00000
where in binary it's: 11110000000000000000000000
each bit represents: ZYXWVUTSRQPONMLKJIHGFEDCBA

If you were to download the latest TweakUI, there you would find an option to hide drives. You can also disable Network Neighborhood (OS dependent). I haven't taken the time to figure what registry keys/values all the TweakUI options affect. On my lockdown boxes, I simply install TweakUI and set my options.

I believe the NoDrivesAutoRun value simply affects the behavior when you inset a CD with an Autorun.inf file.

I suggest that when you find a registry key/value you want more info on, try searching for it on TechNet.

I encourage you to look into system policies (WinNT/95 - PolEdit.exe) or group policies (Win2k - GPEdit.msc). They have what you're looking for. You can try ripping the reg key/value from the .adm file once you find it.

Sorry, I won't do the leg work for you. I'm a lazy 'teach a man to fish' kind of guy. Have fun.
