Maybe, but the behavior of squid is always the same, no matter if I put the log files, the (read-only, empty) disk cache and the rest of squid's stuff in /var on the tmpfs or not.
Probably I forgot something to move to tmpfs, but outside of /var and /tmp there should be no place where programs write "/var" things?
When I shutdown squid there is almost no spinning up. (There is, in "bad" moments, when going online off offline by isdnutils, for example.)

No, I'll try it.

I think so, but it should support transparent proxy. I think you can't take any proxy and use it as a transparent proxy, or am I wrong?
