Welcome to the club - these things drive me crazy.

Beyond the values listed for the circuit I'm wondering if it

Actually, yes. Electrolytics used in synth modules are bipolar (a + side
and a - side). Ceramics, metal film, ... are not bipolar. There are
others here who are much more qualified than I to expound on capacitors.

Also some of the capacitors required are listed

Not dumb questions at all. The cap's with voltages most likely refer to
the radial electrolytics. These are typically specified with 2 values,
Farads (or nano-..., ...) and voltage. Higher voltages are typically ok
to use, but the higher the voltage, the larger the electrolytic so try to
stay with the recommendation so that the electrolytics are good neighbors
to nearby components.

Specifically for the STeiner, Bob Knarley has a parts page at:

He also has parts for some other CGS modules.

Parts for some modules can also be found on one of Larry Hendry's pages:

HOpefully this will get you started, Jeff
