building modular, need schematics, etc

I'm starting to prepare for building a modular synth and have the
following questions.
1) Exactly where can a person get ordering information for the ASM-1
stuff. I've found data at:
http://www.it.kth.se/~e93_mda/synths/companies/stopp/
but no ordering/pricing info. Front panels?
2) Where can a mere-mortal buy CEM, SSM chips or should I stay away
from them due to hard-to-get-ishness?
3) Are there public-domain schematics that are descrete (opamps,
r,c,q,etc) and/or CEM/SSM based?
4) Are most people using 1/4" jacks for audio & control, or bannana
jacks for cv, or what? Is 3.5mm same as 1/8"?
5) Any benefit of shielding cv cables? Can audio patch cables be
unshielded?
6) When using 1/4" jacks for cv, don't you short the cv to ground at
every insert? I guess this is acceptable?
7) I've seen several CV levels used 0-5,-5-+5,0-10, etc. What's
good/common here?
8) What do the modular moogs use for jacks, cv levels?
9) Are schematics (books, mags) available for the Formant system?
10) Is there a source for raw keyboards (no case) ? Prefer to buy
straight from a manufacturer, not surplus.
100) Is this enough questions?
Thanks,
Roger
