data = urllib.urlencode(values)
req = urllib2.Request(url, data)
response = urllib2.urlopen(req)
the_page = response.read()

Answer 1

looks like I needed to stringify it as JSON (which I knew, but didn't know how). Thanks to Tim G. for the assist.

So here's the functional code:

import urllib2
import json

url = 'https://hooks.slack.com/services/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'
values = {"username": "webhookbot", "text": "This is posted to #general and comes from a bot named webhookbot.", "icon_emoji": ":ghost:"}

data = json.dumps(values)
req = urllib2.Request(url, data)
response = urllib2.urlopen(req)
the_page = response.read()
