问题
Other than PORT, MONGO_URL, where can we find the documentation for all the environmental variables that's exposed by Meteor?
In the Meteor docs, I can only find this line
PORT=3000 MONGO_URL=mongodb://localhost:27017/myapp node bundle/main.js
Is there a variable that combines all the JS files and minifies them?

I've been using grasp to answer your question. Here is the command line I used:
grasp -reo --no-line-number --no-color --no-filename process.env.__ . 2> /dev/null | sort | uniq | cut -c 17-
And here is the result on the devel branch:
_
ADMIN_APP
APP_CONFIG
APPDATA
AUTOUPDATE_VERSION
BIND_IP
COMP_CWORD
COMP_LINE
COMP_POINT

Most of thoses environment variables are not documented yet.
About minifing all js and css files, you can use the --production parameter:
meteor run --production
To get the documentation use the --help parameter:
meteor run --help

The easiest way to discover what exists "under the covers" of any open source project is to look at its source code. A simple grep "process.env" * at the top of the meteor source tree will show you every instance of Meteor's use of the process environment.
Alternately, you can visit Meteor's github and search for 'process.env'. Doing this should display thirty matches.
